Most sophisticated and intelligent musician

I interpreted the post as asking about traits of the person, not of their music.

So I did not include intelligent musicians that do not come across as sophisticated in general as people, even if I might think their music is sophisticated as a result of their intelligence .

Neil Young

This is silly but ...
1. Leonard Cohen
2. Bob Dylan
3. Jon Anderson
4. Joni Mitchel
5. Laurie Anderson

My vote is a DEFINATE NO on Kurt Cobain on the intelligence
measure.

Hulk Hogan

@Sit: Yes, this is a bit silly. It's difficult to have an opinion about someone's "intelligence" based on their artistic expression.

I agree that Leonard Cohen is a bright man. Very well spoken and thoughtful. I add him to my list. :)

I have issue with Curt Cobain, too. It's important to remember that he left family, fans, wife and child with his burden. A true intelligent and caring person would have been more thoughtful of himself and the people around him. Suicide is never a smart move, no matter who it is, and what they accomplish. :(
