Gray Area Arts & Technology is a newish venue, admittedly a work in progress, with construction and renovation continuing when the doors are closed, but they are already booking unique electronica acts. My first visit was, as it happens, the first time Tim Hecker played a show in San Francisco (late July; great waves of processed sounds), and my second, Tuesday night (Sept. 23), was one of the five stops on Arca’s current DJ tour along the West Coast.
