Mascis' legendary stoner roots have never been so fully exposed. If jam bands jammed this hard and long, hippies would be extinct, and nobody would mess with the longhairs who remained. A mere seven songs into its 40 minutes, Witch's self-titled debut kicks off with "Seer," an eight-minute trudge through hell. The fact that Mascis isn't wielding the axe is strictly a formality; guitarist Asa Irons plays almost exactly like him, alternating sludgy riffs and discordant leads. In "Hand of Glory," he follows a borderline-jazz scale with a minute-long bloody-fingered frenzy. If Dinosaur never records another album, Mascis has a new tyrannosaurus.
