“During the first Fluxus concert, held in Wiesbaden, Germany, in 1962, Paik performed La Monte Young’s text-based score Composition 1960 #10 (to Bob Morris), which reads, “Draw a straight line and follow it.” Paik dipped his head into a bowl of ink and proceeded to produce a line with his hands, head, and necktie as he moved down the length of a large sheet of paper laid on the floor. This performance—which gained notoriety for Paik’s rather flamboyant interpretation and execution—became known as Zen for Head.” [credit]—
