Marrow Deep

Marrow Deep serves as the ninth studio album from the American progressive metal band Mastodon, arriving on August 28, 2026, through Loma Vista Recordings. This record stands as a somber turning point for the group, marking their first release recorded as a five-piece following the death of founding guitarist Brent Hinds in 2025. The sessions took place throughout that year with producers Patrik Berger and Kurt Ballou, integrating new members keyboardist João Nogueira and guitarist Nick Johnston to expand the sonic palette beyond traditional guitar-driven arrangements.

Thematically, the twelve-track collection functions as a direct exploration of grief, drawing from frontman Brann Dailor's loss of his mother alongside the recent passing of Hinds. Critics described the work as equal parts crushing and cathartic, noting Troy Sanders' vocal performance as potentially the best of his career. Lead single Your Ghost Again introduced fans to this emotional core, while Snakes for Dinner featured a collaboration with Josh Homme that added significant weight to the proceedings.

The band supported the release with the Poisonous Weapons tour, which included Deafheaven and Alcest as special guests. Commercially, the album appeared in multiple formats including a standard CD priced at $14.98 and limited vinyl variants. In October 2026, just weeks after the initial drop, the group announced a highly exclusive Bone Dust edition limited to 170 copies, incorporating actual fossilized mastodon teeth ground into the wax.
