 What you just heard was the track Eternal Rhythm Part One by Don Cherry off of the 1969 album Eternal Rhythm. This album was recorded November 11th and 12th, 1968 at the Berlin Jazz Festival. It features, well, what you just heard in particular was a wonderful flute solo at the end of that, performed, of course, by Don Cherry, but alongside flutes of which he plays, I guess, sort of a typical flute as well as a bamboo flute, a metal flute, and a plastic flute.
