The latest release from Red Mass kicks off with the bluesy groove-mare “Mule Stone Hourly.” Above a froth of warbling riff and fuzz, bandleader Choyce calls across the muck. “I work these hands/Bloody hands,” he moans, breaking off into a Sabbathy solo overlaid with searching slide guitars far from the flesh and far into the ether. From here, we hear a rasping spoken lament for Arlis Perry, a woman murdered by ice pick at Stanford University in 1974, intoned over a crackling bed of white noise and sonic hiss-flames. There’s also a bleakly romantic reflection on mercy — the ugly, Nick Cave-ian kind — and the jingle-stomper “Mamie’s Got the Moves,” a “Papa Oom Mow Mow” for a generation of consumptives. It’s the happiest song on a tape called Sadness, and yet somehow it prowled my dreams, lingering and restless, for weeks.
