Pioneering video artist Valie Export‘s “Space Seeing/Space Hearing” (1973-1974) is edited from a performance piece in which she was recorded by four cameras. The position and distance between the camera and the artist determined what synthesized sound was played, “creating melody from spatial relationships,” according to the curators of a recent exhibit titled Centre Pompidou Video Art 1965-2005 that included Export and other avant-garde video practitioners like Nam June Paik, Bill Viola, and Jean-Luc Godard.
