Best keyboard player?

[Crimson King]

Keith Emerson hands down, he's done it all: plays pretty much every kinda keyboard known to man, greap musical chops, great showman (played on a suspened piano spinning around, would do all kinds of abuse to his keyboards (kicking,shaking,hitting with drumsticks and even stabbing them w/knives!), but the most amazing thing I've seen him do is take a keyboard and play classical pieces backwards! There is a Youtube video of the Atlantic 40th Anniversary where he does some of this incredible backwards playing on the tune "America", Carl Palmer plays an incredible drum solo as well, they were billed as "Emerson and Palmer", Lake did not show that night. I've got all the Nice and ELP CD's in my personal collection! Rick Wakeman is a close 2nd.
