From a 1968 New York Times article on mixed-media events in the New York downtown scene:
USCO, or the Us Company, was a collaboration between the poet and media artist Gerd Stern and the electrical engineer and audiovisual designer Michael Callahan, who got his start as the first technical director of the hallowed San Francisco Tape Music Center. Let's hope that the psychedelic Confidets campaign figures in a future season of Mad Men.
