Mastodon have announced that their new album, Marrow Deep, will feature Black Sabbath bassist Geezer Butler, Gojira frontman Joe Duplantier, Lamb of God vocalist Randy Blythe and Clutch’s Neil Fallon, among other guests.

The band previously released “Snakes for Dinner,” a new song from Marrow Deep featuring Queens of the Stone Age frontman Josh Homme. Mastodon revealed the additional guest lineup in an interview with Kerrang!.

Fallon previously collaborated with the Atlanta metallers on their classic “Blood and Thunder.”

Butler’s involvement held particular significance for drummer/vocalist Brann Dailor, whose late mother, Michele Jeanne Lawrence, was a major fan of the Sabbath legend.

“She was always like, ‘[Butler] writes the lyrics!'” Dailor says of his mother. “She would absolutely love the song. It’s still a pinch-me moment on the record. He could have just hit an open A, and I would have still been like, ‘FEATURING GEEZER BUTLER ON THE OPEN A!'”

Dailor’s mother died in February 2025. One month later, Mastodon announced that founding guitarist Brent Hinds had departed the band, before Hinds died in a motorcycle accident in August 2025.

“As we go forward, we will always carry and [recognize] Brent’s legacy, without a doubt,” says bassist/vocalist Troy Sanders. “We’ll never deny how huge of an influence, and how massive he was in the creation of Mastodon. But through the tragedy, there is triumph.”

“I’m proud of us for not just feeling overwhelmingly pitiful for ourselves, or just collapsing and saying, ‘Hey, we had a good run,'” Sanders continues. “It would be doing a massive disservice to our own being to not continue – there’s so much life in us.”

Marrow Deep is scheduled for release on Aug. 28. Mastodon will begin a U.S. tour in September.
