Hushed and Grim is Mastodon's eighth studio album. It was released on October 29, 2021, through Reprise Records. The album is the band's longest project to date, approaching an hour and a half, and their first double album. Guest appearances include Soundgarden's Kim Thayil on "Had It All" and Troy Sanders' mother Jody Sanders on French horn. There is no guest vocal appearance by Scott Kelly from Neurosis for the first time since their 2002 debut Remission, due to Kelly's withdrawal from the public eye that was not announced until August 2022, and the controversy surrounding him. The album also serves as a tribute to Mastodon's former manager Nick John, after his death from pancreatic cancer in 2018. The band attributes John's passing as the thematic lyrical inspiration for the album. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
