Death Valley Girls feels less like a band and more like a travelling caravan. At their core, vocalist/multi-instrumentalist Bonnie Bloomgarden and guitarist Larry Schemel channel Death Valley Girls’ modern spin on Fun House’s sonic exorcisms, early ZZ Top’s desert-blasted riffage, and Sabbath’s occult menace. Their relentless touring schedule means that the remainder of the group is rounded out by whichever like-minded compatriots can get in the van.
