Yes, it's an excellent solo. Thanks to Allen for posting.
I'm old, but only got seriously into jazz this century, starting in the early oughts. I very early on read a lot of WM's polemics, and they turned me off to such an extent that I never really considered exploring his music. But I've never trashed his music, just the polemics.
Still don't care to purchase recordings, but will explore some stuff of the appropriate vintage on Youtube and the like (not into streaming).
