Anyone familiar the Mingus song, "Open letter to Duke" from Mingus Ah Um? Go listen to the last minute and a half or so of that song. Theres two parts at the end that sound like something out of a island swing-bop bar thing. The first part almost sounds like a classical music arrangement mixed with jazz, and the second part is very tropical sound. Both parts are really layered. I'm guessing Duke Ellington would be a good place to look. Any particular albums or songs of his that have that kind feel? What about other artists/albums?
