This is John Zorn's infamous turn-on-a-dime band. Although they can play any style of music, the majority of their songs are noisy and complex. At any moment, a beautiful melody can degenerate into a hurricane of white noise — and then suddenly switch to something else. They've taken everything aggressive about jazz and heavy metal, blended it together, and tightened it. They look like a rock band: drums, electric guitar, bass, keyboards, and saxophone.
The band formed in 1988, playing live before they recorded their first album under John Zorn's name ([m=15553]). They recorded their final album in December of 1992.
