Anyone who's gone camping or spelunking knows that our senses become heightened in pitch-black darkness. In Root Division's Blackout exhibition, more than a dozen resident and guest artists have created site-specific installations that play with this sensitivity to the dark. In tune with the winter months' light-deprived stretches, the gallery's exhibition space has been converted into a nocturnal environment "lit" only by the glowing artworks and ambient sound. Opening reception performers include psychedelic noisemakers Lemonade, ambient explorers 3 Leafs, and multimedia thespians the elastic future theater company — all of whom present works exploiting their cave-like surroundings.
