Mammoth has parted ways with touring drummer Garrett Whitlock, the band said in a statement. Nathan Bulla will take over drum duties as the group resumes its The End tour on Oct. 31 in Santiago, Chile. The statement gives no reason for the lineup change.
Mammoth, the band led by Wolfgang Van Halen, has parted ways with touring drummer Garrett Whitlock and named Nathan Bulla as his replacement for upcoming shows. The change is set to take effect when the band resumes its The End tour on Oct. 31 in Santiago, Chile, before continuing to Europe.
In a statement reported by Consequence, Mammoth said the departure was agreed to “amicably.” The band thanked Whitlock for his time with the group and wished him well, but did not give a reason for the split. Whitlock had played drums with Mammoth on tour since 2021.
Bulla, whose prior credits include Intervals and Protest the Hero, will handle drums on the scheduled tour dates. Mammoth’s touring lineup is listed as Van Halen on lead vocals and guitar, Frank Sidoris and Jonathan Jourdan on guitar, Ronnie Ficarro on bass, and Bulla on drums.
The band is scheduled to support Iron Maiden at two shows in Chile before heading to Europe for a run of dates from early November through mid-December. The source report also lists Canadian shows with Theory of a Deadman in March 2027 and several U.S. headlining dates later that year.
A Change Before Mammoth’s Tour Resumes
The departure changes Mammoth’s live lineup just as the band is due to return to the road, including support appearances with Iron Maiden in Chile and a European run. Naming Bulla in the same announcement gives the group a replacement for those scheduled performances and signals that the touring plans are continuing with a new drummer.
For fans attending upcoming shows, the practical effect is a lineup change behind the drum kit; the source does not report broader changes to the tour. The announcement also distinguishes the live band from Mammoth’s studio setup: Wolfgang Van Halen records the project’s instruments and vocals himself, while the touring version performs as a full group.

Whitlock’s Place in the Live Band
Mammoth is the recording and touring project of Wolfgang Van Halen. According to the source report, Van Halen plays every instrument and sings on the studio recordings, while concerts feature a band lineup that includes guitarists, a bassist, and a drummer.
Whitlock joined the touring lineup in 2021 and had performed with the group through the period before this announcement. Mammoth’s current road schedule begins with the Chile dates at the end of October, then moves to Europe in November and December. The report names Bulla as the drummer for the continuation of the tour and for the upcoming listed dates.
““Touring drummer Garrett Whitlock and Mammoth have agreed to amicably part ways.””

Reason for Whitlock’s Departure
Mammoth has not explained why the partnership ended, and its brief statement does not indicate whether the decision was prompted by scheduling, personal circumstances, or another factor. The band described the parting as amicable, but no further details were provided in the source report.
It is also unclear whether Bulla’s appointment covers only the dates currently listed or represents a longer-term touring role. Neither a statement from Whitlock nor additional details about the lineup beyond the announced tour have been included in the supplied reporting.
Bulla’s First Scheduled Dates
Bulla is scheduled to join Mammoth for the tour’s Oct. 31 return in Santiago, Chile, including the band’s two announced support shows with Iron Maiden. The group is then set to play European dates from early November through mid-December. Mammoth directed fans to its website for the full schedule and VIP information.
The next listed plans are Canadian shows with Theory of a Deadman in March 2027, followed by several U.S. headlining performances. The supplied report does not specify dates for those U.S. shows or say whether the lineup could change again after the current tour.
