Feeling a little unkempt spiritually? Listen close: Collective Frequency has something to clean you right up. This Sunday, Aug. 26 the group hosts a galactic sound bath at Tortuga Gallery. Using crystal bowls and harps, a xylophone, tang drum, chimes, gongs, rainsticks and more, the group guides visitors through a sound healing session that aims to tap directly into your DNA through the mystical frequencies created. An hour and a half—from 6:30 to 8pm, ought to have you stepping out into the night feeling cleansed. At $10, this sound bath will recharge you better than getting sloppy drunk at a bar show, and with none of the hangover.
