Mammoth, Wolfgang Van Halen’s band, has parted ways with touring drummer Garrett Whitlock, according to a band statement reported by Consequence. Nathan Bulla will take over on drums for the continuation of the group’s tour, beginning Oct. 31 in Santiago, Chile.
Mammoth, the band led by Wolfgang Van Halen, has parted ways with touring drummer Garrett Whitlock and will bring in Nathan Bulla for its upcoming shows. The change takes effect with the continuation of the band’s tour on Oct. 31 in Santiago, Chile, according to a statement published in a report by Consequence.
The band said Whitlock and Mammoth had “agreed to amicably part ways” and thanked him for his time with the group, while wishing him well in future work. The statement did not give a reason for the departure. Whitlock had been Mammoth’s touring drummer since 2021.
Bulla, whose credits include Intervals and Protest the Hero, is scheduled to take on drum duties for the upcoming dates. Mammoth’s touring lineup is listed as Wolfgang Van Halen on lead vocals and guitar, Frank Sidoris and Jonathan Jourdan on guitar, Ronnie Ficarro on bass, and Bulla on drums.
Mammoth is due to support Iron Maiden at two shows in Chile before continuing into Europe. The supplied report lists a European run from early November through mid-December, followed in March 2027 by Canadian dates with Theory of a Deadman and several U.S. headlining shows. The band directed fans to its official website for dates and VIP information.
A New Drummer for Mammoth’s Tour
The change puts a different drummer in Mammoth’s live lineup as the band enters a busy run of international dates. With the first listed performance set for Oct. 31 in Santiago, Bulla is expected to join the touring group immediately rather than at a later point in the schedule.
The move concerns the band’s live performances, not a reported change to its recording setup. Wolfgang Van Halen handles every instrument and vocals in the studio, according to the source report, while Mammoth performs as a full band on tour. The new appointment therefore affects the group’s concert lineup and its presentation of material onstage.

Whitlock’s Place in the Live Band
Mammoth is the musical project of Wolfgang Van Halen. The source report describes it as essentially a one-person studio project, with Van Halen playing all the instruments and singing on recordings, and a full ensemble performing the music live.
Whitlock had served as the group’s touring drummer from 2021 until this announcement. The band’s statement describes the split as mutual and amicable but provides no further account of how the decision was reached. Bulla’s prior associations with Intervals and Protest the Hero are the credentials cited in the report.
The announcement comes before a sequence of shows that includes the Chile dates with Iron Maiden, a European tour in November and December, and planned 2027 performances in Canada and the United States. Those bookings make the timing of the personnel change relevant to fans following Mammoth’s live schedule.
““Touring drummer Garrett Whitlock and Mammoth have agreed to amicably part ways.””

Reason for the Departure Unstated
The band has not publicly explained why Whitlock is leaving, and its description of the split as amicable is the only characterization provided in the cited report. No further comments from Whitlock are included in the source material.
The report identifies Bulla as the drummer for upcoming dates, but does not say whether he is joining permanently or only for the current touring schedule. It also does not describe any changes to Mammoth’s studio plans or provide additional details about the band’s future lineup beyond the listed touring personnel.
Chile Opens the Next Tour Leg
Mammoth’s next reported appearances are two support dates with Iron Maiden in Chile, with the tour continuation beginning Oct. 31 in Santiago. The band has said it will move on to Europe shortly afterward, with the source report placing the European dates from early November through mid-December.
Further ahead, Mammoth is scheduled to play Canadian shows with Theory of a Deadman in March 2027, along with several U.S. headlining dates. Fans can check the band’s website for its published schedule and VIP information.
