George Maciunas was the founding member and leader of the most radical and experimental art movement of th 1960s: "Fluxus". Associated with artists such as Joseph Bueys and Yoko Ono, Fluxus rejected traditional systems of high art and practised a form of "anti-art" encompassing everything from photography and pavement art to poetry and drama. This biography of one of the key figures in the history of 20th-century art recounts in text and archive photographs the life story of this contradictory and unorthodox man. Emmett Williams provides anecdotes and impressions from former Fluxus colleagues and other friends (and enemies), to produce a portrait of this crusader, whose mission was to change the world - beginning with the world of art. Although tempered with wit and wisdom, his iconoclasm won him few friends amongst the art establishment during his lifetime, but Fluxus prevailed as an acknowledged force behind the upheavals in the art of the 20th century.
