As if this year's lineup wasn't already stacked enough: Austin Psych Fest's LEVITATION 2015 just became even more can't-miss, with the addition of hometown legends the 13th Floor Elevators, playing their first show in nearly 50 years. HEALTH, DIIV, S U R V I V E, Ryley Walker, and others also join the bill. And, a reminder: you can still win weekend passes for this year's fest right here.
