My favorite is probably Ray Manzarek. Also like Keith Emerson, Dennis DeYoung, Rick Wakeman, and Steve Walsh.
And you can't top Billy Joel for piano. There's just no way.
I'd be a pretentious ******* and mention someone like Jelly Roll Morton or Fats Waller, but both of the aforementioned pianists are good in their own right
also, to the fighter discussion, Killer Instinct
Ok I'm back. Commence the disagreeing.
No I can see that he/she (I can't really tell) has talent, but I respectfully disagree. There are lots of good piansts however, there are very few that have such an amazing caliber as an Emerson or a Joel.
No disrespect however to your choice.
