Count me in as a big fan of Miles in Berlin. I love the Sam Rivers date, but as was mentioned earlier, Wayne was definitely the missing piece of the puzzle, and at least for me, hearing Berlin just gives the sense of everything coming together.
The dates with George Coleman for me are the least satisfying. Don't get me wrong, I'm a huge fan of George, but just not with this band. It still makes for some fine jazz, but with that rhythm section, its hard not to hear the sound of a band being held back.
