Sources: 57. Developments: 10. Heavy metal band Mastodon released their ninth studio album, ‘Marrow Deep’, via Loma Vista Recordings. The 65-minute project serves as a tribute to founding guitarist Brent Hinds, who passed away on August 20, 2025, following a motorcycle accident in Atlanta. The album features the current five-piece lineup, including guitarist Nick Johnstone and keyboardist João Nogueira, and includes contributions from collaborators such as Josh Homme and Geezer Butler. In September 2026, the estate of Brent Hinds filed a civil lawsuit in Fulton County, Georgia, against the remaining band members. The legal action, filed on September 3, centers on disputes regarding unpaid ownership stakes and the unauthorized use of Hinds’ likeness. The estate alleges that Hinds maintained ownership interests in the band and its related businesses because he had not signed a buyout agreement prior to his death. While the band reportedly issued an $80,000 check as a buyout, the estate claims they have not cashed it, pending a full accounting of the actual value of Hinds’ shares. Furthermore, the estate is seeking damages for the use of Hinds’ image to promote the ‘Marrow Deep’ album and associated merchandise. In a social media statement, Mastodon denied the allegations, describing the matter as a ‘private business dispute’ and calling the lawsuit ‘meritless’. The band stated they intend to vigorously defend themselves but will not comment further to honor Hinds’ memory. ## Claims - Brann Dailor suggested that late guitarist Brent Hinds might not have liked the band's new album.
