(Crystal Ballroom, 1332 W Burnside) Maturity has come quickly for Pennsylvania psych-pop group Dr. Dog. Amassing an almost immediately rabid fanbase seemed inevitable upon their inception in the late '90s, with an innately good live show, and the underground success of 2005's Easy Beat providing a primer to the band's '60s rock allegiances. Follow-ups Fate and We All Belong found the band more willing to stray from its overt influences, incorporating the more raucous elements of their live show into their records—this approach assured the mainstream success of fourth LP Shame, Shame, too. Dr. Dog's upcoming Be the Void feels less like the Kerouacian doctrine that the name might suggest, with sunny pop-rock ("That Old Black Hole"), big psych-guitar-and-organ slow jams ("Vampire"), and a return to their lo-fi roots on the excellent—and most single-worthy—"How Long Must I Wait."
