Three bassists converged on WNUR Studios, in Evanston, Illinois in 1998 to record these tracks, finally released after 16 years: 5 freely improvised trio sessions, 6 miniatures suggested by Kowald and performed by the trio, and 6 duos between Kowald and Lonberg-Holm.

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.
