William Richard Frisell is an American jazz guitarist. He first came to prominence at ECM Records in the 1980s, as both a session player and a leader. He went on to work in a variety of contexts, notably as a participant in the Downtown Scene in New York City, where he formed a long working relationship with composer and saxophonist John Zorn. He was also a longtime member of veteran drummer Paul Motian's groups from the early 1980s until Motian's death in 2011. Since the late 1990s, Frisell's output as a bandleader has also integrated prominent elements of folk, country, rock ‘n’ roll and Americana. He has six Grammy nominations and one win.

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".
