Terry Riley Don Cherry Duo (2017)

"This was recorded February 1975 at two different days/locations in Germany (A-side on 23rd in Cologne, B-side on the day before in Godorf). There are several bootlegs of these recordings that differ in media and cuts, there never was any official release though. The Cologne performance was filmed for the TV show "Nachtmusik im WDR" and presumably broadcasted (live?). It took place in the same venue (Großer Sendesaal) where Keith Jarrett's famous The Köln Concert was recorded the month before. Don Cherry is credited playing tambura - but he plays the Doussn'Gouni." (Rate Your Music)
