oh boy - this is right in my wheelhouse - i love my keyboards...
let's start with "watcher of the skies" or "firth of fifth" by genesis - there are many more by tony banks.
then pretty much anything from keith emerson of elp, but perhaps "karn evil 9" is his best - on brain salad surgery, the only album that i had to buy twice, as i wore out the first copy.
alaska by the band u.k. - also many more by eddie jobson.
rick wakeman - solo or with yes - too many to mention;
"lingus" by snarky puppy - one of the great keyboard moments in recent music - do yourself a favor.
"spartacus" by triumvirat - love that album, even tho it's a rip off of keith emerson's sound.
jacob collier is an up and coming genius in the music world and it is disgusting how good he is at his age.
toujour l'amour by procul harem - and conquistador, of course.
a whole bunch of stuff by return to forever, ambrosia, zappa, tull (especially thick}, spock's beard (the light or the doorway) - not to mention the obvious ones - billy joel, elton john - and the classics, fats waller, oscar peterson...
