Bandoneon
A black and white photograph of Fred Waldhauer with David Tudor, who is working with elements of his sound system for his 9 Evenings work, Bandoneon!, at a technical rehearsal in September 1966. Waldhauer, seated at center, is a light-skinned man with close cropped hair and glasses. An accordian-like obejct sits on his lap, and the floor around him is littered with a tangle of wires and cords.
