Rok, that was a highly relevant question in regard to where the "new jazz" was created. When I was traveling a lot, and going to clubs, the music was different everywhere I went. In none of the places would I consider the new music any better, it was all good, just different; Atlanta was different from LA, and Chicago different from St. Louis. Although I've never been to New York, they seem to think what ever originates there has or should set the standard; "It ain't necessarily so."
There was even a difference in jazz from E. St. Louis and St. Louis, Mo. The jazz from E. St. Louis was the most individualistic, it was the most "Afrocentric", while jazz from the other side of the river was what you call "jazz jazz"; closer connected to "Bird" and that lineage. Jazz from E. St. Louis had no lineage, which is why when I went to a new lounge and heard a new group, I was floored; they used instruments like the African finger piano, and unusual drums.
The only group I know from St. Louis that has recorded and played consistently over the years, that I heard a lot live, was the "Trio Trebien". There is no group I've heard live more times than I've heard these guys. This same tune on my CD sounds much better; while I like everything on the CD, this is my favorite tune.

I don't approach music from an intellectual point of view; Ambrose's music seemed to wander, at times like one band was playing two different tunes. Maybe at another time in a different mood I might like it.
Rok, I know your thoughts on later day Trane and Miles.
Enjoy the music.
