The everything else of Zorn's output is just that... everything. The man is so prolific it would be nearly impossible to cover everything. This is a sampling of some of the more common "everything else" you might run into, from free improv (Euclid's Nightmare, Ganryu Island), to hardcore/thrash jazz/ambient (Painkiller) to noisy Etudes for solo guitar (The Book of Heads).
