Vegas band Panic! at the Disco plays behind its fourth studio album, Too Weird to Live, Too Rare to Die! Given the outfit's affinity for exclamation points, maybe it's just too darn excited. But we won't fault it for that; we're sure it makes for a jolly-good show. Ohio's Walk the Moon does shamelessly large-scale synth-pop, coming off like an indie Duran Duran with U2-size ambition.
