SPIN. Dancer and choreographer Trisha Brown has always experimented with ways to combine the normal everyday activity of the human body with impossible-seeming dance moves. (For instance, an early work featured a man walking down the side of a New York building.) In this triptych, Brown recorded her own movements by pirouetting on three softgrounded copper plates placed on the floor, knowing all the while that the finished work would be seen on the wall. This change in perspective and shifting perception may help viewers look at dance and art in a new way. Brown is a Washington State native who currently lives in New York.
