Film Walk
Film Walk is perhaps the one plus ultra of this branch of projection performance, treating the projector literally as an instrument. In this work, which has varied in form across several years,Lee threads 16mm film through only the sound head of a projector tuned on its side, bypassing the projector’s gate. This film is double-perf, meaning a second row of sprocket holes runs along the side of the strip where that soundtrack would normally be. As these pass over the sound head, they produce an electronic purr, or, when amplified enough, an unpleasant metallic grinding comparable to the sound of a buzz saw. Lee pulls the film through the projector by hand, yanking it roughly through the sound head. The variations in speed that result from Lee’s manual movement of the filmstrip cause abrupt changes in the frequency and timbre of the sprocket sound. (Jonathan Walley, Cinema Expanded)
