Musicians who have created something as special solo as they did with their well-known band.

I wonder if any of the greats have made a solo record as good as the one with their best-known, classic band?

Because when I think about it, very few have come close. Roger Waters, for example, or David Gilmour couldn't make a record as good on their own as they did with Pink Floyd. Maybe Peter Gabriel is the closest to that. I also remembered Paul Simon as a good example.

So I'm curious, who do you think have done it?

edit: Be sure to post specific albums you think are so good, not just artist/band!

edit 2: Please read the whole post, Classic Rock(yeah, it's that topic), name the specific album(s), and studio albums only, thx!
