Dual female vocalists keep the cacophony from crashing in on itself, and the swinging drummer maintains a sensible dance beat. The kids like that, dancing. At least I do. I've kept their latest EP, "Montigola Underground," on heavy rotation for about two weeks leading up to their March 24 show at Swingers. If they pack half the wallop live, you should probably leave your medicated and/or easily upset friends behind for this one. Sunday night at 9 with The J.Rawls. w.m.
