Recorded during the 2002 studio sessions that yielded the albums A Short Visit to Nowhere and Broken English, this unreleased recording of a Mars Williams composition is issued as a 1-sided LP with the stellar lineup of Brötzmann with Williams, Ken Vandermark, Jeb Bishop, Fred Lonberg-Holm, Kent Kessler, Michael Zerang, Hamid Drake, Mats Gustafsson and Joe McPhee.

Recording in Graz, Austria in 2019 at the club Tube's, Chicago alto saxophonist Dave Rempis and drummer Michael Zerang, frequent collaborators with Ken Vandermark and The Resonance Ensemble, joined with Austrian improvising and classical pianist Elisabeth Harnik to record three exuberant and incredibly informed improvisations: "Triple Tube" I through III.

Captured at Elastic in Chicago, the free improvising trio of Katherine Young on bassoon & electronics, Michael Zerang on percussion, and Michael Foster on soprano & tenor saxophones, use contrasting timbres and techniques throug wind instruments, percussion and electronics to create unusual and captivating dialog, evolving with great composure, a sense of wonder, and mastery.

In 2000, saxophonist Mats Gustafsson and curator John Corbett organized a 16-piece free music big-band featuring key members of the Chicago and Swedish scenes, recording these two impressive, ecstatic, and explosive works.
