Here's a Swedish TV documentary about Don Cherry. Filmed for the most part in the US and on the island Cherry was living with his family during the 1970s.
With Rashied Ali, James Blood Ulmer, Nana Vasconcelos, Denis Charles, Huss Charles a.o.
Especially the music by Cherry, Ali and Ulmer is great IMO. Sadly it seems there's no other recorded evidence of this trio.
Produced and directed by Urban Lasson
