At first, it's hard to tell what South African artist Tracey Rose is doing in TKO, her grainy, black-and-white DVD projection. You hear her breathing and moaning, and every once in a while, her naked body emerges into focus. She's boxing ruthlessly with the camera—four cameras, actually—and she's going to continue to the point of screaming, orgasmic exhaustion. The woman is a champ.
