Mammoth and touring drummer Garrett Whitlock have agreed to part ways, the band said. Nathan Bulla will take over drum duties as the band continues its tour, including Chilean dates with Iron Maiden and a European run.
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 comes as the group continues its tour, with performances in Chile and a European run scheduled in the coming weeks.
The band said it and Whitlock had “agreed to amicably part ways” and thanked him for his time with Mammoth. It did not give a reason for the departure. Bulla, whose past associations include Intervals and Protest the Hero, will take over drum duties beginning with the continuation of the tour on October 31 in Santiago, Chile.
Mammoth is scheduled to support Iron Maiden at two shows in Chile before beginning a European tour in early November, running through mid-December. The touring lineup listed by the band consists of Wolfgang Van Halen on lead vocals and guitar, Frank Sidoris and Jonathan Jourdan on guitar, Ronnie Ficarro on bass, and Bulla on drums.
The band also has dates planned for 2027: a series of Canadian shows with Theory of a Deadman in March, along with several U.S. headlining performances. Mammoth directed fans to its website for tour dates and VIP information. The announcement does not specify whether Bulla’s appointment is limited to the currently scheduled dates or extends beyond them.
A Change Before Major Tour Dates
The personnel change arrives just before a busy stretch of live performances, including two support dates with Iron Maiden and Mammoth’s European tour. Naming Bulla ahead of those shows gives the group a drummer for the announced itinerary and makes the lineup change relevant to fans planning to attend.
It also distinguishes Mammoth’s touring lineup from its studio approach. Wolfgang Van Halen records the band’s music by playing the instruments and singing himself, while live performances use a full group. A change in drummer therefore affects the band’s concert lineup, even though the source report does not describe any change to its recorded work or release plans.

Questions About the Drummer Change
The band has not disclosed why Whitlock and Mammoth parted ways, and the statement offers no details beyond describing the decision as amicable. Whitlock has not been quoted in the supplied report, so his perspective and plans are not available here.

Bulla’s First Mammoth Dates
Bulla is scheduled to make his first appearance with Mammoth on October 31 in Santiago, Chile, as the band resumes the tour. Mammoth is then expected to play its two Chilean support shows with Iron Maiden before beginning its European dates in early November and continuing through mid-December.
The band’s later plans include the March 2027 Canadian shows with Theory of a Deadman and several U.S. headlining dates. Mammoth’s website is the cited source for the schedule and VIP information. Whether Bulla will remain the drummer for those 2027 performances has not been stated.
