Milford Graves was an American jazz drummer, percussionist, Professor Emeritus of Music, researcher/inventor, visual artist/sculptor, gardener/herbalist, and martial artist. Graves was noteworthy for his early avant-garde contributions in the 1960s with Paul Bley, Albert Ayler, and the New York Art Quartet, and is considered to be a free jazz pioneer, liberating percussion from its timekeeping role. The composer and saxophonist John Zorn referred to Graves as "basically a 20th-century shaman."

Albert Ayler was an American avant-garde jazz saxophonist, singer and composer.
