Indian Jewelry's Free Gold! combines gauzy, desert-rock drones with warped vocals that sometimes loop and melt as if playing from a record left too long in the hot sun. But beneath the heatstroke and haze, Indian Jewelry's songs are simply catchy, slightly sinister pop. From the far opposite end of the experimental spectrum come Eats Tapes, whose all-analog, acid-touched hyper-rave workouts should leave you adequately parched for the headliners.
