Mastodon are preparing to release their first album since the departure and death of co-founder guitarist/singer Brent Hinds last year. The hard-charging band’s ninth studio album, Marrow Deep, is due out on Aug. 28 through Loma Vista Recordings.

The collection, which comes five years after their final effort with Hinds, 2021’s sprawling double album Hushed and Grim, was inspired by the Three Fates of Greek mythology “and the fragile threads connecting life, loss and destiny,” according to a release.

The album’s first single, the furious, five-minute prog metal rager “Snakes For Dinner,” features guest backing vocals from Queens of the Stone Age’s Josh Homme, with a release promising “a staggering roster of guests” to be revealed soon. In addition to founding members bassist/vocalist Troy Sanders, guitarist/vocalist Bill Kelliher and drummer/singer Brann Dailor, the album is the first full-length to feature guitarist Nick Johnston, as well as keyboardist João Nogueira. It was recorded at the group’s own West End Sound Studio in Atlanta and co-produced by the band with Patrik Berger (Lana Del Rey) and Kurt Ballou (High on Fire).

“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,” said Sanders in a statement. “That’s a magical feeling that makes us keep wanting to go to band practice. It’s reminiscent of the very beginning of our band, where all members are hungry, we’re united, and excited to get to work. And we’re thrilled to have the opportunity to do this record.” 

The three original band members recently paid loving tribute to late guitarist Hinds in the emotional 35-minute short film “The Mastodon in the Room,” in which they recall the good, and the challenging, times with their beloved bandmate, who they describe as a sweet, but often volatile presence who struggled with mental health and substance use issues.

“Snakes For Dinner” is the follow-up to last month’s surprise single “Your Ghost Again.” Mastodon will hit the road starting in September for the Poisonous Weapons tour featuring support from Deafheaven and Alcest. Check out the full list of dates below.
