An international network of artists, composers and designers noted for blending different artistic media and disciplines. The Fluxus movement... developed its 'anti-art', anti-commercial aesthetics under the leadership of George Maciunas. The movement, which still continues, played an important role in the opening up of definitions of what art can be. The origins of Fluxus lie in many of the concepts explored by composer John Cage in his experimental music of the 1950s. Fluxus encouraged a “do-it-yourself” aesthetic, and valued simplicity over complexity. Like Dada before it, Fluxus included a strong current of anti-commercialism and an anti-art sensibility, disparaging the conventional market-driven art world in favor of an artist-centered creative practice.
