Correction to my last post: a classical musician has to have incredible talent and feel as well; except there is no music written down, and no repetition with an improvising jazz musician, and that's the primary distinction.
Any time a man can get on a stage and wow an audience of critical "hard bop" fans, playing extemporaneously, he has a talent beyond my comprehension.
No put down of classical musicians meant.
Enjoy the music.
