Masada is a musical group with rotating personnel led by American saxophonist and composer John Zorn since the early 1990s.

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".
