"We thank Garrett for his time with MAMMOTH and wish him the best in all his future endeavors.

"Nathan Bulla (INTERVALS, PROTEST THE HERO) will be joining us for drummer duties with the continuation of 'The End' tour beginning October 31st in Santiago, Chile and moving on to Europe shortly after.

"Check mammoth.band for all the dates and VIP information.

"See you out there!!"

As previously reported, MAMMOTH will film its London, United Kingdom headline show at O2 Shepherd's Bush Empire on Tuesday, November 24.

Before London, MAMMOTH will join DEEP PURPLE on the road for four U.K. arena shows, a chance for anyone who misses the O2 Shepherd's Bush Empire to still catch the band and experience their live magic. They then head to Ireland for two headline dates, including a rescheduled Belfast show.

The rest of MAMMOTH's current touring lineup consists of Wolfgang on guitar and lead vocals, Frank Sidoris (SLASH FEATURING MYLES KENNEDY AND THE CONSPIRATORS) on guitar, Jon Jourdan on guitar and vocals, and Ronnie Ficarro on bass.

MAMMOTH's third album, "The End", came out last October. The 10-track effort clocks in at 39 minutes and showcases the evolution of Wolfgang and his songwriting since he launched his solo career in 2020. Recorded at the legendary 5150 studio, the album was produced by friend and collaborator Michael "Elvis" Baskette.

Continuing the tradition of writing all the songs and performing all the instrumentation and vocals himself, Wolfgang Van Halen set out to challenge himself beyond what he did on his debut and sophomore release, "Mammoth II". From the hypnotic opening of "One Of A Kind" to infectious closer "All In Good Time", Wolfgang demonstrates his proficiency as a musician and songwriter. Songs like "Same Old Song", "Happy" and "Selfish" fit perfectly alongside older songs that fans had already come to love from MAMMOTH.

Back in 2021, MAMMOTH's first offering, "Mammoth WVH", took flight, bowing at No. 12 on the Billboard 200 and capturing No. 1 on three Billboard charts — Top Hard Rock Albums, Top Independent Albums, and Top Rock Albums. "Distance" soared as the first of two No. 1 rock radio hits and earned a Grammy Award nomination for "Best Rock Song". Two years later, "Mammoth II" only saw Wolfgang pick up the pace. It debuted in the Top 5 of the Billboard Top Album Sales chart in addition to bringing him back to No. 1 on the Top Hard Rock Albums chart. Inciting widespread applause from Rolling Stone, Guitar World, Grammy.com, Kerrang! and more, Classic Rock hailed it as "a solo second that betters his debut in every department," and American Songwriter applauded, "'II' reveals a closer representation of what MAMMOTH is now and Van Halen's dynamism as a musician and as a writer." The band canvased the globe with METALLICA, supported FOO FIGHTERS in North America, supported CREED on their record-breaking tour as well as filling houses on their own. They performed on NBC's "Today", ABC's "Jimmy Kimmel Live!" and at the 2024 MusiCares "Person Of The Year" benefit gala in honor of Jon Bon Jovi. Not to mention, Wolfgang shared the stage with Ryan Gosling, Mark Ronson and Slash at the 2024 Academy Awards performing "I'm Just Ken" from the blockbuster "Barbie" movie. He also joined Maynard James Keenan (TOOL, A PERFECT CIRCLE),Chad Smith (RED HOT CHILI PEPPERS),Robert Trujillo (METALLICA) and producer Andrew Watt for the Rock And Roll Hall Of Fame induction of Ozzy Osbourne that same year.
