The two Last Exit tracks are from the Koln album, a live recording dating from Feb 1986, originally released by ITM in 1990. The eight tracks by the Brotzmann/Laswell duo are from the 1987 studio recording originally released in that year on Celluloid.
When it comes to avant-garde jazz-rock noise, few bands kicked out the jams better than did Last Exit. A who's who of jazz players with punk-ass attitudes, Last Exit -- guitarist Sonny Sharrock, bassist Bill Laswell, drummer Ronald Shannon Jackson, and saxophonist Peter Brötzmann -- could swing, rock, and create an all-out free jazz din all in the blink of an eye. - Allmusic.com
