Marrow Deep arrives August 28 and marks the first Mastodon full-length since 2021, featuring new guitarist Nick Johnston and a production team including Kurt Ballou and Patrik Berger.
Mastodon have announced Marrow Deep, their first full-length since 2021’s Hushed and Grim. Out August 28 via Loma Vista Recordings, the news comes with new single Snakes For Dinner, which features Josh Homme of Queens of the Stone Age – his first appearance on a Mastodon recording since Colony of Birchmen on 2006’s Blood Mountain.

The album arrives in different circumstances for the Atlanta band. Founding guitarist Brent Hinds passed away in 2025, and last week the band released The Mastodon in the Room, a short film documenting the grief and complexity surrounding his absence. Marrow Deep is the other side of that, with guitarist Nick Johnston joining as a full member alongside keyboardist João Nogueira, and the band’s own account of the sessions suggests the new lineup hit the ground running.
“Bill, Brann, and myself are thrilled that we still have the opportunity to do this, and we’ve got other members who are just over the moon to be in the band with us,” says Troy Sanders. “It’s reminiscent of the very beginning of our band, where all members are hungry, we’re united, and excited to get to work.”
Snakes For Dinner follows lead single Your Ghost Again, which ranked second in Revolver’s reader poll of the best songs of 2026 so far. Both tracks pull from the album’s central themes, surrounding the Three Fates of Greek mythology as a lens for processing loss, absence and what comes next.
Mastodon co-produced the record at their own West End Sound studio in Atlanta with Patrik Berger (Lana Del Rey, Charli XCX) and Kurt Ballou (High On Fire, Converge). Andrew Scheps, whose credits include Adele, Black Sabbath and Metallica, handled the mix. A guest roster beyond Homme is yet to be revealed.
Marrow Deep is out August 28. Pre-orders and pre-saves are live now at mastodonrocks.com.
