Most sophisticated and intelligent musician


Let's stay with not classical musicians.
It's John McLaughlin for me.

Pierre Boulez has more intelligence, taste and has acheived more, than ALL the others mentioned put together.
Dr. Billy Taylor.
He was a great musician and educator. He brought the Jazzmobile to New York City.
There are some accomplished works of art around that are sophisticated, even technically daunting but not necessarily enjoyable - subjectively of course.

In fact, sophistication sometimes is achieved with the compromise of melodic flow - the antidote of "Easy listening".

Those I found to be sophisticated, intelligent and enjoyable at the same time with *some* of their works:

Arvo Part
Enrico Rava
Sting
Miles Davis
Norman Winstone
Patricia Barber
Kenny Wheeler Quintet
Charles Lloyd
