Charlotte Moorman (1933–1991) was a Juilliard-trained cellist, avant-garde performance artist, and longtime collaborator of Korean-American artist Nam June Paik.  Moorman and Paik began their relationship after meeting at the 1964 New York Avant Garde Festival, which Moorman herself had organized. Through her performance of Fluxus compositions, Moorman forged a unique career in the gray area between composer and performer.

Dick Higgins was an early member of Fluxus and one of its most important contributors. He was a writer, publisher, artist, and composer who studied with John Cage. In 1961 Higgins began his series of Danger Music scores. Not without their typical Fluxus whit, humor, ideas of chance and indeterminacy, as well as challenges to what a score, source, and music might be considered, Higgins took these scores further by creating actions with the real possibility of danger for performer or audience – in some cases to the extent that some works are unlikely to ever be performed.

In the 1960s and 1970s, Peter Moore (1932-1993) was the photographer of record for the documentation of the avant-garde art scene in downtown New York. He is recognized for his photographs of dance and theater performances as well as the ephemeral events of the Fluxus movement including performances by George Maciunas, Allan Kaprow, Nam June Paik, Joan Jonas, Charlotte Moorman among many others.
