Book excerpt: George Maciunas was the founder and leader of a radical and experimental art movement of the 1960s known as Fluxus--which rejected traditional high art to practice an extraordinary form of anti-art. Maciunas attempted to rule Fluxus in totalitarian fashion, yet he laughed at himself and called forth laughter in others. This biography reveals the story of an unorthodox, contradictory, and elusive genius. 107 illustrations.
