In regard to the bigger questions that have consistently been raised on this thread, such as old jazz VS new jazz, I think each individual will have to answer that question for themselves.
With me, it's all music, and the "old stuff" that's locked in a vault, shall remain there; any new music does not necessarily have to fall into a "genre", but can fall into one of two categories; "like", and "don't like".
Enjoy the music.
