The Crystals, Crystal Method, Crystal Antlers, Crystal Stilts, Crystal Castles: Do you have Crystal Confusion? To keep it simple, only one such band—Los Angeles trio Crystal Antlers—visit the Triangle this week. But they don't make identification much easier, as they've spent their career bounding from headstrong rock bruisers to hazy-headed psychedelic workouts, with manifold departures and trips in between. At least this year's Nothing Is Real pulls the reins a bit tighter, with a handful of would-be rock radio hits where the singing has gusto and the production has muscle. If you like the idea of a mixtape containing songs by Weezer, Black Lips, Women and The Walkmen covered by an anxious lot of sweaty dudes, you'll find Nothing Is Real to be perfectly legitimate. Portland's Lovers make dangerous, seductive and highly referential pop noir, a little like Suicide with a touch of brown-sugar sweetener.
