PERFORMANCE: The Lab has been celebrating their 25th anniversary this month. Tonight, composers Miya Masaoka, founder of the San Francisco Gagaku Society, and Tomas Philips will perform. Phillips' performance will consist of an extended version of his 2007 release, Drink_Deep. "Utilizing a series of low frequencies, isolated microsounds and minimal tones, the piece attempts to generate an immersive sound environment that allows space for the listener to be an active participant in the music, thus inviting a particular quality of engagement beyond the confines of conventional listening."

7:30 p.m. // The Lab (2948 16th St) // $8-12, sliding scale
