My favorite Jazzer. His drumming makes my spine tingle, its so creative. Listening to Joe solo is like listening to good poetry. It's very lyrical and intense. Even though he is not known as a big solo guy, He is damn good at them. Most drum solos/breaks I hear feel like a pause in a song rather than a progression. Joe's solo's and breaks truly bring the song to another level. For example, my favorite drum solo;
This 1964 drum solo in the song "Sound of the Loop" is my favorite. It's incredibly musical. The intro is awesome aswell.
[Edit] also check out these drum breaks in Brubecks cover of "Take the A Train". Taste, personified.
