This rolling, blaring work of art pops up at just about every social-justice event in town. Crafted out of a wheeled trash can, powered by a car battery and equipped with some big-ass speakers, the TAZmaniac Sound System has become one of the activist community's most efficient means of raising a ruckus. (Hell, the thing pumps out enough bass to make a lowrider jealous.) Whether it's playing funk music or broadcasting a demonstrator's voice, this boombox instantly signals the creation of a Temporary Autonomous Zone, all the while reminding us of how much waste we produce. (When's the last time you recycled?) TAZ's owners prefer to remain anonymous, and we can respect that, so long as they promise to keep pumping out the jams.
