Most sophisticated and intelligent musician


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