Not that howling guitarist Amber Valentine isn't striking in her own right. But drummer Ed Livengood, playing like a Muppet on crank, continually draws attention as he hammers his drum kit like a flailing octopus with a flip-top head. Between them, they produce a barrage of sweltering, sludgy rock in the tradition passed from Black Sabbath to the Melvins to Kyuss. Jucifer is monolithic, from its stage packed with amps to its psychedelic snarl. Picture that.
