ART: Artists Ian Coyle, Tyrone Davies, and Adam Prince will transform the San Francisco Art Institute's Swell Gallery into The Dance Show, an elaborate assemblage of rooms, stages, dance floors, and lounges. The audience is encouraged to interact with the installation, which uses themes indiscriminately borrowed from "club culture, popular music, film, drug culture, and pie in the sky techno-utopias."
