'It was in San Francisco at a punk festival. I was already high and the air was so thick in the rooms that you could cut it with a knife. I had a photograph camera with me; I stood in a corner of the entrance hall and took 36 pictures on slide film. At home I put the slides into a slide projector. I took out the lens and filmed the slides by filming directly from the projector - using single frames according to a certain plan.'
