Tornano in circolazione in via semi-ufficiale le registrazioni di Terry Riley in duo con Don Cherry, effettuate a Colonia (Germania) nel febbraio 1975. Le raccoglie B.Free con il titolo Terry Riley Don Cherry Duo. Ricorda Riley: "I was staying at Mary Bauermeister’s house. She was the ex-wife of Karlheinz Stockhausen. Don was staying there a lot. A German producer asked us to do a concert in Cologne that was recorded for radio, I don’t know who got hold of the tapes from the radio, but the recording sounds fairly decent. We didn’t plan anything. The best recording from those sessions is when I’m playing Persian Surgery Dervishes and Don is playing along, creating a countercurrent for it."
