Panic! at the Disco + Neon Trees

The Vegas band Panic! at the Disco (recently reunited with its irritating exclamation point) plays behind its new one, Vices and Virtues. Opening are Utah alt-rockers Neon Trees, who got bumped up to the big leagues a couple of years ago after being plucked by the Killers to open an American tour; the band plays from last year's debut LP, Habits.
