Ghosthouse, thanks for those Jamal clips. Fantastic! Had not heard those and they are interesting to me in that they show Jamal playing in a somewhat different style from the chord-heavy approach of "Poinciana" days; more use of melodic lines in the right hand. Great player. I particularly enjoyed "Trio-Patterns" and beautiful rendition of "Stolen Moments" with a unexpected lilt and slightly faster tempo compared to the classic original:

Combine this with very interesting and sometimes complex structures in their compositions and virtuosic playing and it pushes the broader "jazz" button for me. Whatever it is, it's really good music. Towner is a monster musician and a driving force in the group.

What I think makes a good point for this thread is that while being so intent on pointing out what is not jazz (in your opinion only) you overlook great stuff like the Jamal clips. I think we are probably due for the twentieth posting of Ravel's "Bolero"; or perhaps more Billy Ocean or Luther Vandross. Now, THOSE will really get my feet and fingers tapping on two and four ☺️. You can join the party anytime. Cheers.
