Prism by Keith Jarrett album Changes

This is a beautiful song by Keith (p), with Gary Peacock (bs) and Jack Dejohnete (dr). Melody is beautiful and melancholic . I like all the development of improvisation Keith (2:02), to increasing intensity until his apotheosis. At 3:37 his expression seems an orgasm! Gary improvisation is inspired (4:14) and I particularly like the passage in 4:47. I feel there is a symbiosis between musicians and see the song as an organism. ECM records 1984
