John Zorn is an American composer, conductor, saxophonist, arranger and producer who "deliberately resists category". His avant-garde and experimental approaches to composition and improvisation are inclusive of jazz, rock, hardcore, classical, contemporary, surf, metal, soundtrack, ambient, and world music. Rolling Stone noted that "[alt]hough Zorn has operated almost entirely outside the mainstream, he's gradually asserted himself as one of the most influential musicians of our time".

Downtown music is a subdivision of American music, closely related to experimental music, which developed in downtown Manhattan in the 1960s.
