Barrytown, NY: Printed Editions, 1982
30.5 x 23cm, 4pp folder content of four, colour transparencies (each uniformly 30 x 22.5cm) silkscreened with a pattern of arrows. The overlays are designed to be placed on any other piece of piano music and the sonata is created by the musician following the newly re-arranged score (moving from phrase to phrase as s/he reaches a new arrow). A pure Fluxus work. Some slight browning to the folder but otherwise very good.
