Mammoth, Wolfgang Van Halen’s band, has amicably parted ways with touring drummer Garrett Whitlock. Nathan Bulla will take over on drums for the continuation of the band’s tour, which is scheduled to resume Oct. 31 in Santiago, Chile.
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 dates. The change is set to take effect with the continuation of the band’s tour on Oct. 31 in Santiago, Chile, ahead of scheduled shows in Europe.
In a statement reported by Consequence, Mammoth said Whitlock and the band had agreed to an amicable split. The group thanked him for his time with Mammoth and wished him well. The statement did not give a reason for the departure, and neither side’s further explanation was included in the report.
Bulla, whose credits include Intervals and Protest the Hero, is joining the touring lineup for the upcoming run. Mammoth’s announced touring members are Van Halen on lead vocals and guitar, Frank Sidoris and Jonathan Jourdan on guitar, Ronnie Ficarro on bass, and Bulla on drums.
The group is scheduled to support Iron Maiden at two shows in Chile before moving on to European dates from early November through mid-December. The band’s statement directs fans to its website for tour dates and VIP information. Further details about the drummer change beyond the announcement have not been reported.
A Touring Lineup Change Before Chile
The change puts a new drummer into Mammoth’s live lineup just as the band is due to resume touring, including high-profile support dates with Iron Maiden in Chile. Bulla will also be expected to join the group for its planned European run, making the switch relevant to fans attending those shows.
Whitlock had been Mammoth’s drummer since 2021, according to the source report. His departure marks a change in the band’s touring personnel, while the announcement does not indicate a change to the project’s studio arrangements or to its other listed touring members.
Mammoth’s live performances involve a full band, while Van Halen plays the instruments and sings on the studio recordings. That distinction means the announced replacement concerns the touring lineup; the source does not report any effect on recording plans or unreleased music.

Whitlock’s Role in Mammoth
Mammoth is the project led by Wolfgang Van Halen. The source report describes it as essentially a one-man studio project, with Van Halen playing every instrument and singing on recordings. For concerts, he performs with a band that includes guitarists, a bassist, and a drummer.
Garrett Whitlock joined the touring lineup in 2021 and had played drums with Mammoth until this departure. Bulla’s past work with Intervals and Protest the Hero is cited in the announcement as background to his appointment. The reported details establish his prior band associations but do not describe his role in Mammoth beyond taking on touring drum duties.
The October 31 start date begins the continuation of Mammoth’s The End tour, according to the band’s statement. After the Chile shows, the itinerary is reported to include European dates from early November to mid-December, followed by planned Canadian shows with Theory of a Deadman in March 2027 and several U.S. headlining dates.
“Touring drummer Garrett Whitlock and Mammoth have agreed to amicably part ways.”
— Mammoth, in a statement quoted by Consequence
Reason for Whitlock’s Exit
The announcement does not explain why Whitlock and Mammoth parted ways, and it does not include comments from Whitlock. The band describes the decision as amicable, but the report provides no additional detail about how it was reached or when it was finalized.
The published information also does not specify whether Bulla’s appointment is permanent or limited to the announced touring dates. It confirms that he will handle drum duties for the tour’s continuation, but offers no longer-term lineup plans. The source does not report changes to Mammoth’s recording plans.
Tour schedules can change, and the band directs fans to its website for current dates and VIP information. The report gives a broad European window—early November through mid-December—but does not provide the full list of venues and dates in the supplied material.
Bulla’s First Scheduled Dates
Bulla is scheduled to make his Mammoth touring debut with the continuation of The End tour beginning Oct. 31 in Santiago, Chile. Mammoth is then expected to play two Chilean support dates with Iron Maiden before its European run, which the report places from early November through mid-December.
Further ahead, Mammoth has planned Canadian shows with Theory of a Deadman in March 2027 and several U.S. headlining dates. The source material does not give full date and venue details for those later shows. Fans can check Mammoth’s official site for the current itinerary and VIP information.
There is no announced timeline for further comments from Whitlock or the band about the circumstances of the split. The next public indication of how the lineup change is working will be Mammoth’s performances with Bulla, beginning with the scheduled Chile dates.
