Levitating Platters

Haunting, staccato organ opens Black Mountains' fourth LP, after which "Mothers of the Sun" erupts elemental guitar crunch and a supersonic solo, and genre-bender "You Can Dream" mops psych doom with synth-popped pulses. In a thoughtful, albeit morbid, rendezvous recount, "Cemetery Breeding," the Vancouver quintet explores well beyond by-the-book psych rock. Stephen McBean and Amber Webber's vocals instantly hook, the latter's lungs emitting as unique and mighty as Grace Slick. Cosmic and eerie, the disc pays ample homage to the influences from whom IV swipes its title. (Sat., 10:45pm, Elevation Amphitheater)
