Following 2011's The Hunter, Mastodon will release their next full-length, 《Once More 'Round the Sun》, on June 24 via Reprise. Produced by Nick Raskulinecz (Deftones, Alice in Chains), Once More Around the Sun is "60-or-so minutes of pure, authentic Mastodon," as singer/bassist Troy Sanders told Paste. According to Paste, "Diamond in the Witch House" features guest vocals from Neurosis' Scott Kelly.
