"A one-minute take was made of my head twisting from side to side at a rapidly increasing rate, stopping only after I went as fast as I possibly could. This was then re-recorded by camera from a monitor with the action being gradually slowed down to play at a constant rate in time with a series of loud regular beats. Using the alarmingly small tape-speed knob on the 1970s Sony edit deck to progressively slow down the action, the movement of the head stretches the ability of the record-head drum to coherently represent the action, while also displaying its own technical limitations."
