FRANK, Judge.
A jury convicted Gregory Leon Young, appellant, of armed robbery in violation of Code § 18.2-58 and sentenced him to life in prison. On appeal, appellant contends that the trial court erred in allowing the Commonwealth to play portions of [622]*622a videotaped confession to the jury because it contained statements of other, unrelated crimes that were inadmissible and highly prejudicial. For the reasons stated, we affirm appellant’s conviction, but vacate appellant’s life sentence and remand to the trial court for re-sentencing.
BACKGROUND
On January 21, 2004, at 3:00 p.m., a man entered the Check 'n Go check-cashing facility in Danville, Virginia. Shanna Jones, an employee, was alone in the store, standing behind the counter. The man approached Jones and placed a small note on the counter that read, “I have a gun. Give me $2,100.00. You have ten seconds.” The man told Jones, “Just give me all your money and you won’t be hurt.” He then pulled from his coat a large silver and black handgun. The man pointed the gun at Jones, and she handed over all of the money in her cash drawer, totaling $1,176. The man left the store. Jones pressed the panic button at her station to alert police, who responded to the scene. A video camera in the store recorded the robbery.
On January 28, 2004, police officers arrested appellant in Henry County, Virginia, in connection with a bank robbery that occurred that same day. During their interrogation of appellant regarding that offense, appellant made statements regarding the robbery of the Check ‘n Go in Danville. After being questioned by Henry County detectives regarding the Danville robbery, Danville detectives questioned appellant and took a written statement from him. Appellant was subsequently charged with armed robbery and use of a firearm in commission of a felony. These charges were tried separately, with the armed robbery tried by a jury.1
Before trial began, outside of the presence of the jury, the Commonwealth advised the trial court that they would seek to [623]*623admit a video recording of appellant’s confession to Henry-County and Danville detectives. The tape contained two different interviews, one conducted by Henry County/Martins-ville detectives, and one conducted by Danville detectives. The total interview lasted approximately four hours and addressed not only the subject charges, but other, unrelated crimes involving both robbery and drugs, including the Henry County bank robbery for which appellant was initially arrested. Appellant made incriminating statements regarding the present armed robbery during both interviews.
The Commonwealth acknowledged that in the tape “they discuss other things too ... other cases. And I guess what we need to do is try to sanitize it.” Appellant objected to the introduction of the video altogether, arguing that it would jeopardize his presumption of innocence before the jury. The trial court allowed the video into evidence, but limited its use to statements about the present offenses, ruling that evidence of any other crimes was not relevant to the present charges. The trial court advised the Commonwealth that “statements unrelated to these offenses need to be redacted from the tape before it is played to the jury.” The Commonwealth agreed and informed the court that he would instruct the detectives to do so.
After a brief recess and before trial began, appellant renewed his objection to the admission of the videotape and expressed his concern that the recording could not be sanitized in order to exclude the statements of other crimes. The Commonwealth’s Attorney advised the court that detectives were currently reviewing the video and that he would notify appellant as to the outcome of that process before he sought to introduce the video. The trial court agreed and proceeded with opening statements.
During his opening statement, appellant asserted that he was “tricked and forced” into confessing the Check ‘n Go robbery to the detectives. Appellant stated that at the time of his confession he was being “held and detained in Henry County on separate charges.” Appellant also noted that a [624]*624search of his house did not result in the recovery of any weapon or cash associated with the armed robbery.
At trial, the victim identified appellant as the robber, who was depicted in the store video recording of the crime. The Commonwealth introduced the fingerprint analysis from the note the robber left on the counter, which matched appellant’s fingerprints. The Commonwealth also entered appellant’s signed, written confession into evidence, which included a description of the clothing appellant wore on the day of the robbery.
In his cross-examination of the laboratory technician who performed the fingerprint analysis, appellant elicited testimony that his fingerprints had initially been taken for another criminal case. In his cross-examination of detectives who had interviewed him on the day of his arrest, appellant suggested that he had been intoxicated at the time he made incriminating statements, though these witnesses denied noticing any evidence of intoxication.
The Commonwealth represented that the tape had been “sanitized” and proceeded to play portions of the tape for the trial court’s review. The tape had not been sanitized, but the Commonwealth indicated that it would try to “start” and “stop” the tape at specific points in order to allow the jury to view only the statements made regarding the present offense. The Commonwealth and the trial court both noted that the videotape did not have a “counter” that would facilitate this method of showing the tape.
During the “Martinsville” portion of the videotape played for the trial court’s review, appellant made reference to other robberies and said that he had purchased drugs with the money he recovered from the present robbery:
INTERVIEWER: Did you go there planning to rob that too, or did you ... did you have it spur of the moment or was it planned?
APPELLANT: No ... that one wasn’t spur of the moment.
INTERVIEWER: You drive the same ear?
[625]*625APPELLANT: Yeah.
* * * * * *
INTERVIEWER: [W]hat did you do with that money ... eleven hundred dollars?
APPELLANT: And the rest, man, you know, bought me a little bit of drugs, you know ... little bit of crack ... little bit of heroin____
Appellant objected to the statements regarding his purchase of drugs. The trial court overruled appellant’s objections, finding that his use of the proceeds of the crime was admissible evidence. The trial court determined that appellant had “opened the door” by asserting in his opening statement that police had searched his home and had not found any proceeds of the crime. The trial court ruled that the Commonwealth could play the “Martinsville” portion of the tape to the jury.
In considering the “Danville” portion of the videotape, the trial court declined to review the video, noting a concern about making the jury wait for the four hours it would take for such a review. The Commonwealth’s Attorney represented that “I’m pretty sure that they didn’t go into anything else” regarding other crimes, though he conceded that he could not be “a hundred percent sure.” The trial court decided, “[w]ell, on the Danville tape, if there is any mention of anything other than the Danville Check ‘n Go situation, I’m going to ask that the tape be immediately stopped, and if necessary I will ask the jury to disregard what they just saw.”2
[626]*626The Commonwealth resumed its ease, calling the Henry County detective who had interviewed appellant. During his testimony, the Commonwealth played the “Martinsville” portion of the videotape to the jury, which included the statements noted above.
The Commonwealth then played the “Danville” portion of the videotape, which included the following statements by appellant:
INTERVIEWER: What brings you all the way to Martins-ville and Henry County?
APPELLANT: Exactly what I got caught for today.
* * * * * *
INTERVIEWER: For drugs?
APPELLANT: Yeah.
Appellant objected, arguing that the statement was unduly prejudicial and would affect the impartiality of the jury. Appellant further objected to the entry of the “Danville” portion of the videotape altogether, as it was unnecessary to show his taped confession because he had signed a written statement, which the Commonwealth had previously introduced into evidence. The Commonwealth argued that it was necessary to show the tape because appellant had called into question his sobriety at the time of the interrogation through his comments in his opening statement and in his questions on cross-examination of the Commonwealth’s witnesses. The trial court agreed, and overruled appellant’s objection. The trial court then took a brief recess to allow the Commonwealth to further review the video to “see if there’s anything else on here that would be objectionable.”3
When the trial resumed, the court instructed the jury to disregard the question and answer regarding the reason ap[627]*627pellant was arrested on the day of the interview. The Commonwealth continued to play the videotape, which contained the following statement about the previous Henry County robbery: “I got caught redhanded [sic] at this particular job____” Appellant objected, and the trial court instructed the jury as follows:
Ladies and gentlemen of the jury, to the extent this tape we are viewing contains any reference to anything which may have occurred outside of Danville, specifically outside the incident which is at issue in this Court today, the Check ‘n Go ... the alleged Check ‘n Go robbery, it is to be disregarded. It is not relevant to these cases, and it is not to be considered by you as evidence in these cases today.
The Commonwealth resumed playing the videotape to the jury:
INTERVIEWER: One mistake don’t make you bad.
APPELLANT: That was no one mistake.
INTERVIEWER: There have been several.
APPELLANT: I’m pretty sure you are aware of them.
History ... got a bad history.
******
APPELLANT: [T]he thing is now, you know, everybody is thinking as far as you know, the authorities here in Henry County, they’re thinking I’m a serial robber, you know____ [T]his is my first time doing a[sic] armed robbery. I had a robbery charged back in the day, but there was no weapon used ...
The trial court stopped the tape and instructed the jury:
Ladies and gentlemen of the jury, to the extent that there’s any reference to anything that’s not relevant to this proceeding today, it is to be disregarded, as I instructed you earlier. I just heard something on the tape that relates to apparently something about the past, and that is to be disregarded. It is not evidence in this case.
Appellant again objected to the continued playing of the tape to the jury, noting that the jury had again heard an [628]*628inflammatory remark. Appellant asked the trial court to exclude the tape from evidence as it undermined his presumption of innocence. The Commonwealth argued that the only purpose for showing the videotape was to demonstrate that appellant was coherent during.the interrogation, as appellant had “opened the door” through his opening statements and cross-examination of the Commonwealth’s witnesses regarding his sobriety that day. The trial court granted appellant’s continuing objection and refused to allow the tape to be played any further, ruling however that the Commonwealth could offer the remainder of the tape in rebuttal if appellant “put into issue [his] ability to have made the statement.” Appellant renewed his objection to the videotape being played for any purpose.
Appellant also argued that damage had already been done to his presumption of innocence by the evidence of other crimes already heard by the jury, but the trial court ruled that it had “instructed the jury as best it can.” The trial court again instructed the jury to disregard “any reference to any incidents that occurred other than those for which we are in Court on today.”
Appellant presented no evidence. The jury found appellant guilty of armed robbery. At sentencing, the Commonwealth introduced one burglary conviction from 1988, a burglary and a grand larceny conviction from 1988, a burglary and a grand larceny conviction from 1991, a robbery conviction from 1992, and armed robbery and grand larceny convictions from 1993. After deliberating for twelve minutes, the jury recommended appellant serve life in prison.
This appeal follows.
ANALYSIS
On appeal, appellant contends the trial court erred in allowing the admission of videotape evidence that contained statements of other crimes committed by appellant.4 In reviewing [629]*629this argument, we must consider whether: (1) the evidence of other crimes was admissible; (2) the trial court erred in relying on cautionary instructions to remedy the admission of other crimes evidence; and (3) if any error occurred, whether it was harmless.
Admissibility of Other Crimes Evidence
“The admissibility of evidence is within the broad discretion of the trial court, and a ruling will not be disturbed on appeal in the absence of an abuse of discretion.” Blain v. Commonwealth, 7 Va.App. 10, 16, 371 S.E.2d 838, 842 (1988). However, “[b]y definition, when the trial court makes an error of law, an abuse of discretion occurs.” Bass v. Commonwealth, 31 Va.App. 373, 382, 523 S.E.2d 534, 539 (2000).
Evidence that an accused has committed other crimes, “by showing that the accused has a criminal propensity, tends to reverse his presumption of innocence of the crime on trial.” Lewis v. Commonwealth, 225 Va. 497, 502, 303 S.E.2d 890, 893 (1983).
Generally, evidence that a defendant has committed crimes other than the offense for which he is being tried is highly prejudicial and inadmissible. Such evidence confuses the issues before the jury and tends to prejudice the defendant in the minds of the jury by showing his or her depravity and criminal propensity. This rule is not without exception. Evidence of other crimes or convictions may be admitted for the purpose of, among other things, impeaching the credibility of a witness, including a criminal defendant, attacking a defendant’s character on cross-examination, or proving a relevant issue or element of the offense charged, such as motive, intent, common scheme or plan, knowledge or identity.
Hackney v. Commonwealth, 28 Va.App. 288, 293, 504 S.E.2d 385, 388 (1998) (citations omitted).
[630]*630Citing Thornton v. Commonwealth, 31 Va.App. 825, 525 S.E.2d 646 (2000), and Kirkpatrick v. Commonwealth, 211 Va. 269, 176 S.E.2d 802 (1970), the Commonwealth argues that other crimes evidence is admissible because appellant’s statements regarding other crimes were “so interwoven with his overall statement that they could not be completely redacted from the videotape.” This argument is based on an incorrect statement of the law and is without merit. Both Thornton and Kirkpatrick hold that evidence of other crimes can be admitted when the two crimes are so intertwined as to not be easily separated without affecting the propriety of the statement. Here, it is not the crimes that are intertwined, but the statements themselves. This cannot serve as a basis to admit evidence of other crimes.
While the Commonwealth repeatedly acknowledged to the court below that evidence of other crimes had no place in appellant’s trial, they argued that the videotape should be admitted to show appellant’s demeanor during the interrogations.5 They contended below, as they do on appeal, that appellant “opened the door” through his opening statement and his questioning of the Commonwealth’s witnesses by suggesting that his statements were made while he was intoxicated.6
[631]*631Assuming, without deciding, that the portions of the videotape were admissible to show appellant’s demeanor, this does not provide an adequate basis for allowing evidence of other crimes to be admitted at trial. There were other permissible means by which the Commonwealth could have shown appellant’s demeanor. Indeed, the trial court recognized that other crimes evidence could not be admitted, ruling that such evidence was not relevant to the present charges. We agree that the statements of appellant as to other crimes were inadmissible at trial.
Review of the Videotape and Use of Cautionary Instructions
It is within the discretion of the trial court to require the Commonwealth to redact a videotape and to decide whether to review the videotape before it is presented to the jury. “ ‘[T]he conduct of a trial is committed to the trial judge’s discretion, and absent evidence of an abuse of this discretion, we will not disturb his rulings on that subject.’ ” Griffin v. Commonwealth, 22 Va.App. 622, 625, 472 S.E.2d 285, 287 (1996) (quoting Justus v. Commonwealth, 222 Va. 667, 676, 288 S.E.2d 905, 910 (1981)).
The trial court instructed the Commonwealth to redact any statements regarding other crimes from the videotape before it was played to the jury. The Commonwealth failed to do so, as was revealed to the trial court when the Commonwealth played the “Martinsville” portion of the tape for the court. After reviewing the “Martinsville” portion of the videotape, the trial court was on notice that the Commonwealth had not redacted the tape as instructed. The trial court heard statements regarding other crimes on the “Martinsville’’ portion of the videotape, and, thus, should have realized the danger that the jury would hear inadmissible evidence.
[632]*632As a substitute for reviewing the entire videotape outside of the presence of the jury and ensuring the integrity of the evidence presented at trial, the trial court decided to remedy the introduction of any inadmissible statements through cautionary instructions. As a result, the jury repeatedly heard evidence of other crimes, requiring the trial court to issue four separate cautionary instructions.
Generally, a trial court may cure errors arising from inadmissible evidence being improperly presented by promptly instructing the jury to disregard the inadmissible evidence. LeVasseur v. Commonwealth, 225 Va. 564, 589, 304 S.E.2d 644, 657 (1983). “We will presume that a jury has followed the trial court’s prompt and explicit curative instructions, unless the record clearly shows that the jury disregarded the instructions.” Schmitt v. Commonwealth, 262 Va. 127, 147-48, 547 S.E.2d 186, 200 (2001).
However, there are instances in which cautionary instructions given by the trial court regarding inadmissible evidence cannot be presumed to have been followed by the jury-
“[T]hé admission of incompetent evidence is reversible error notwithstanding the fact that the trial court, after its admission, instructed the jury to disregard it, if such illegal evidence was so impressive that it probably remained on the minds of the jury and influenced their verdict.” “If the prejudicial effect of the impropriety cannot be removed by the instructions of the trial court, the defendant is entitled to a new trial.”
Whether a manifest probability exists that the improper evidence prejudiced the accused despite the cautionary instruction depends upon the nature of the incompetent evidence when considered in relation to the nature of the charges, the other evidence in the case, and manner in which the prejudicial evidence was presented.
Mills v. Commonwealth, 24 Va.App. 415, 420-21, 482 S.E.2d 860, 862-63 (1997) (citations omitted).
[633]*633In Mills, we reversed appellant’s convictions for various traffic offenses, resisting arrest, and driving under the influence when the arresting officer testified before the jury to the presence of drug needle marks on Mills’s arms. Id. The trial court’s prompt cautionary instructions to the jury not to consider the officer’s comments were not enough to cure the prejudicial impact on the accused’s presumption of innocence. We held that, “[ajlthough evidence of the defendant’s guilt was overwhelming, we cannot say that the prejudicial evidence did not affect the length of the sentences or the amount of fines that the jury recommended and the judge imposed.” Id. at 421, 482 S.E.2d at 863. Thus, we found that the error was not harmless.
In Powell v. Commonwealth, 13 Va.App. 17, 409 S.E.2d 622 (1991), we similarly held that the admission of other crimes evidence was reversible error despite the cautionary instruction given by the trial court. Powell was charged with various drug violations. Id. at 18, 409 S.E.2d at 623. The prosecutor questioned Powell on cross-examination regarding his prior felony convictions. Id. at 19, 409 S.E.2d at 624. Powell testified falsely regarding the number of prior convictions, and the prosecutor proceeded to question him about the specifics of those convictions, which had involved drug distribution. Id. at 19-20, 409 S.E.2d at 624. The trial court instructed the jury to limit its consideration of prior convictions to impeachment purposes only. Id. at 27, 409 S.E.2d at 628. We held that, despite Powell’s false testimony that allowed for impeachment by the prosecutor, “[t]he risk of prejudice was so great because the evidence portrayed [Powell] as a drug dealer” and its admission constituted reversible error that could not be cured by a cautionary instruction. Id. at 27-28, 409 S.E.2d at 628-29.7
[634]*634Here, the jury heard multiple statements regarding other crimes committed by appellant, including several references to other robberies, the same crime for which appellant was on trial. Henry County detectives questioned appellant about the Danville robbery using references to other robberies, asking if he “used the same car” and if he planned to “rob that [one] too.” In referring to the Henry County robbery, appellant said that he had been caught “redhanded [sic] at that particular job.” Appellant also made reference to Henry County detectives having the impression that he was a “serial robber.” Thus, the jury had evidence before it that appellant was involved in a robbery in Danville. Each statement was accompanied by an admonishment by the trial court that these statements were not evidence against appellant.
The repeated admission of inadmissible other crimes evidence had a cumulative effect on the impartiality of the jury that could not be cured by cautionary instruction. See Maxey v. Hubble, 238 Va. 607, 616, 385 S.E.2d 593, 597 (1989) (holding that where counsel persisted in making objectionable remarks despite the trial court’s admonishments and instructions to the jury to disregard those remarks, “an appellate court will presume that the prejudicial effect of the improper conduct was too strong to be removed by further admonitions or jury instructions”). Under these circumstances, it is impossible to conclude that the jury did not consider these other crimes in determining appellant’s guilt and the length of the sentence recommended. Instead, this “evidence was so impressive that it probably remained on the minds of the jury and influenced their verdict.” Mills, 24 Va.App. at 420, 482 S.E.2d at 862.8 We find that the trial [635]*635court abused its discretion by embarking on a procedural path that relied on cautionary instructions to remedy the erroneous and deliberate admission of other crimes evidence. We further find the cautionary instructions could not remedy this error.9
The only question remaining is whether these errors were harmless as to both the finding of guilt and to the sentence recommended by the jury.
Harmless Error
When deciding whether non-constitutional error is harmless in the context of a criminal proceeding, we must apply Code § 8.01-678 that states in pertinent part:
[636]*636When it plainly appears from the record and the evidence given at the trial that the parties have had a fair trial on the merits and substantial justice has been reached, no judgment shall be arrested or reversed ... [f]or any ... defect, imperfection, or omission in the record, or for any error committed on the trial.
The Virginia Supreme Court stated in Clay v. Commonwealth, 262 Va. 253, 259, 546 S.E.2d 728, 731 (2001), that “[i]n a criminal case, it is implicit that, in order to determine whether there has been ‘a fair trial on the merits’ and whether ‘substantial justice has been reached,’ a reviewing court must decide whether the alleged error substantially influenced the jury. If it did not, the error is harmless.” The Clay Court adopted the following test for non-constitutional harmless error that was applied by the United States Supreme Court in Kotteakos v. United States, 328 U.S. 750, 66 S.Ct. 1239, 90 L.Ed. 1557 (1946):
“If, when all is said and done, the conviction is sure that the error did not influence the jury, or had but slight effect, the verdict and the judgment should stand.... But if one cannot say, with fair assurance, after pondering all that happened without stripping the erroneous action from the whole, that the judgment was not substantially swayed by the error, it is impossible to conclude that substantial rights were not affected----If so, or if one is left in grave doubt, the conviction cannot stand.”
Clay, 262 Va. at 260, 546 S.E.2d at 731-32 (quoting Kotteakos, 328 U.S. at 764-65, 66 S.Ct. at 1248).
We hold that the trial court’s errors were harmless as to the guilt of appellant. Disregarding the videotaped statements, the evidence of appellant’s guilt was overwhelming. Two detectives testified as to appellant’s oral confession to the robbery of the Danville Check ‘n Go in two different interviews with police. In addition, the Commonwealth introduced appellant’s written confession to the crime where appellant described the clothing he wore during the robbery. The jury had the opportunity to view the video recording of the crime, [637]*637where appellant fit the physical appearance of the robber, including the clothing appellant described. Appellant’s fingerprints were recovered from the note the robber handed to Ms. Jones directing her to give him the money. At trial, Ms. Jones positively identified appellant as the man who robbed her, and testified to her prior identification of appellant in a photo array presented to her by detectives shortly after the crime occurred. Given the weight of this evidence against appellant, we find that substantial justice has been reached and the error in admitting evidence of prior offenses in appellant’s guilt phase of the trial was harmless.
However, we do not find evidence of appellant’s involvement with drugs, or evidence of the Henry County offense, to be harmless with respect to the sentence imposed. “[T]he bifurcated procedure established in Code § 19.2-295.1 clearly manifests a legislative intent to provide juries with information specific only to sentencing[.]” Gilliam v. Commonwealth, 21 Va.App. 519, 525, 465 S.E.2d 592, 595 (1996). “[T]he prior criminal convictions of a felon, including previous efforts to punish and rehabilitate, “ ‘bear upon a tendency to commit offenses, the probabilities of rehabilitation, and similar factors’ ” indispensable to the determination of an appropriate sentence.” Id. at 524, 465 S.E.2d at 595 (citations omitted). “We cannot at once reason that such considerations promote enlightened sentencing and dismiss as harmless the prejudicial effects of inadmissible, although facially relevant, evidence pertaining to sentencing issues.” Webb v. Commonwealth, 31 Va.App. 466, 471, 524 S.E.2d 164, 167 (2000).
During the guilt phase of trial, any reference to a prior robbery or to the “serial robber” was harmless as evidence of appellant’s two prior robbery convictions was properly admitted during the sentencing phase. However, allowing the jury to hear of appellant’s drug charge and drug purchases, as well as his robbery offense in Henry County, during the guilt phase was not harmless, as the jury did not hear this evidence during the penalty phase. Further, both of these prior acts [638]*638refer to recent behavior, whereas appellant’s prior offenses occurred in the past, the most recent conviction being in 1993.
Finally, the jury deliberated a mere twelve minutes before recommending appellant serve a life sentence, the maximum penalty for armed robbery. We would usurp the role of the jury to conclude that the sentence would have been the same had the jury not known about appellant’s drug activity and his current arrest in Henry County. We therefore find that the admission of these prior acts into evidence during the guilt phase of appellant’s trial was not harmless error with respect to the sentence imposed.
CONCLUSION
After the Commonwealth and the trial court agreed that evidence of prior crimes was inadmissible, the trial court nevertheless exposed the jury to inadmissible evidence. The court then attempted to cure the error by giving cautionary instructions. We find the trial court erred by employing this procedure. The error was harmless in determining appellant’s guilt, but we find it substantially affected the sentencing recommendation made by the jury. Accordingly, we affirm appellant’s conviction for armed robbery, but reverse and remand to the trial court for re-sentencing consistent with this opinion.10
Affirmed in part, reversed in part, and remanded.
