Okay, not a master class in the traditional sense, but a master class performance. See what sophisticated, well-skilled, jazz artists do with a simple, done-to-death tune. The interaction of the band, alteration of the form, dynamics, return to the head, hell, Jamal's piano playing is a course in itself, and it's in CONTEXT! OMG! The bassist has what I'd call a non-traditional 2-finger right-hand technique, but, the guy grooves, has great presence through out. Personally, I'd give his technique a pass but see what you think. Watch the drum kit solo. Dyamm! Reminds me of Liebman, Potter, Rufus. So far to go.
