Take Roky Erickson in pill form and a dram of diluted acid rock, throw in some stoned boogie woogie, and log a doctor's name or a cab company in your phone for the morning, because there's a psychedelic cataplasm draped over the side of the Williamsburg Bridge, and it's dripping all over your face. Representing the borough's percolating psych scene this time around are headliners Madam Robot and the Lust Brigade (freakin' out!), Traveling Circle (where is my mind?), the Runaway Suns (like woah), Heavy Hands (Uluru as limb), and Asteroid #4 (you got your acid in my pop), among others. Also, the free bouncy ride guy will be there, perhaps in a dolphin suit. Don't fall down.
