***Boston-baked blend of heavy, slime-soaked tones and relentless, pounding rhythms torn up and spit back in your face by a lunatic with a microphone. It’s like Black Sabbath in reverse, a mouth full of bubble gum and broken teeth, or, as Larry Dolman puts it “low-end wind-tunnel electro-punk.” Part of what makes this demented trio’s sound unique is the absence of stringed instruments. Their microphones-and-electronics assault holds its own against heavy, guitar-driven rock.
