"Yesterdays"

"Humoresque" by Antonin Dvorak

Documentary

Billastro

LOL

the one name I tried to put on my list, but I like the others too much.

Tatum was a beast

I'm not familiar with those names. Anyway, I am more familiar with Mozart and Franz Schubert

All genres? Victor Borge

Seems pretty subjective. I can't even pick out the top junko piano player... Professor Longhair? Dr. John? James Booker? Booker would get my vote.

I don't know how to define "best". I know that I'm really moved by Thelonious Monk. His touch, his negative space... Does negative space even count toward figuring out the best player? I think that has more to do with composition.

Vladimir Horowitz
Johnnie Johnson
Barry Cuda

No particular order they all have or have had their many moments of brilliance.

Andre Watts
Eldar Djangirov
Chick Corea
Lang Lang
My Grandma Ritchie

I like your list and am also moved tremendously by Monk's work.

Would definitely add Jimmy Smith, too! (Gregg's hero)
