Mastodon will release their ninth studio album, Marrow Deep, on August 28 via Loma Vista Recordings. This marks the group’s first full-length project since the 2021 double album Hushed and Grim and follows the death of longtime guitarist and vocalist Brent Hinds. The band will support the new record with a North American tour beginning in September.
A New Chapter for Mastodon
Following the loss of co-founder Brent Hinds, the remaining founders members—bassist and vocalist Troy Sanders, guitarist and vocalist Bill Kelliher, and drummer and singer Brann Dailor—have moved forward with a revamped lineup. The new album features guitarist Nick Johnston and keyboardist João Nogueira as members.
Recording for Marrow Deep took place at the group’s own West End Sound Studio in Atlanta. The production team included the band members themselves, alongside collaborators Patrik Berger, known for his work with Lana Del Rey, and Kurt Ballou of High on Fire.
Thematic Inspiration and Sound
The band describes Marrow Deep as a thematic exploration of the Three Fates from Greek mythology, focusing on the concepts of life, loss, and destiny. The album’s lead single, "Snakes For Dinner," features guest backing vocals from Josh Homme of Queens of the Stone Age.
The band recently honored Hinds’ legacy through an emotional 35-minute short film titled The Mastodon in the Room. In the film, Sanders, Kelliher, and Dailor reflect on their history with Hinds, addressing both his creative contributions and his personal struggles with mental health and substance use.
