Most sophisticated and intelligent musician

Let's stay with not classical musicians.
It's John McLaughlin for me.
Keith Jarrett, without a doubt, he's the most intelligent musician that ever lived. Who else on the list can play classical equally as well as jazz? The man's a genius, but he's often moody...but then again reportedly so was Beethoven!
I think Mr Jarrett should be called Dr Jarrett, as he can sure
cure my Insomnia,lol...................
Bobby McFerrin gets my vote for most intelligent vocal artist. Just picked up VOCAabuLarieS and it's simply brilliant. Music & Sonics - 10+++
