Ja Ja Ja Ja Ja, Nee Nee Nee Nee Nee, 1969

This edition by Joseph Beuys is a sound installation consisting of a stack of 20 felt plates in which a tape is embedded. The recording documents a Fluxus performance from 1968 in which Beuys, together with Henning Christiansen and Johannes Stüttgen, rhythmically repeated the words "Ja" ("yes) and "Nee" (“no”) for almost an hour. The monotonous, mantra-like recitation creates a hypnotic effect that takes the listener out of the usual stream of thought. The felt panels reinforce this meditative effect by creating an atmosphere of rapture through their isolating and calm presence.
