The document discusses the Fluxus movement, an international network of artists, composers and designers in the 1960s known for blending different artistic mediums and disciplines. It notes that Fluxus developed an "anti-art" aesthetic under the leadership of George Maciunas and staged avant-garde performances in several cities. Many experimental artists of the time, like Joseph Beuys, Yoko Ono and Nam June Paik, participated in Fluxus events.
