Though I cannot say I know much about Fundacja Słuchaj’s background, I can say that their releases tend to be excellent, releasing some of the bigger names in improvisational music.  This collection is no different.

The personnel on this four-disc set is pretty phenomenal: Rafał Mazur plays bass, Satoko Fujii plays piano, Guillermo Gregorio wields the saxophone, Natsuki Tamura and Artur Majewski perform on trumpet and Ramón López fills out this group on drums and percussion.
