Track 3 "Ostinato" from this CD. A very exciting track with powerful trumpet playing over a strong rhythm section pattern which combines elements of swing and Latin. Not going back and forth between the rhythmic patterns but somehow combining them. The track is structured rather than free but very adventurous and forward looking. In fact, the whole album is excellent. Jazz music at a very high level of invention. I've just listened to it 3 times. Maybe my favorite Ellis. Great sound, too.
Don Ellis trumpet; Paul Bley, piano; Gary Peacock, bass; Gene Stone or Nick Martinis, drums.
