Like the unruly cousin of Queer Voice at ICA last spring, Quadruple-Consciousness at Vox Populi offers a look at artists who use parody or hyperbole to critique American culture. Much of the work by the 19 artists is performance-based, with two nights of live performance central to the show. (If you missed the opening night, you can catch different performers live at the show’s closing on Jan. 29.)
