An international group of artists working between the 1960s and early 1970s who renounced traditional forms of music and theater and instead explored the mundane and chance aspects of sound, film, and performance, evoking the rebelliousness of Dada. Although the American artist and composer George Maciunas in 1962 published a manifesto explaining the movement’s experimental aspects under the rubric Neo-Dada, Fluxus resisted a formal agenda, spreading largely through spontaneous protean events referred to as happenings.
