Demonspell
cheating the polygraph
Focusing on keyboardists who help define a band's sound without lapsing into self-indulgence (relatively anyways, as this is a prog-metal focused list!):
Sverd
Martin Hedin (Andromeda)
Fredrik Hermansson (Pain Of Salvation)
Richard West (Threshold)
Michael Pinella (Symphony X)
Richard Barbieri (Porcupine Tree)
Kevin Moore
And of course the first generation proggers: Wakeman, Bardens, Banks, Emerson, Kerry Minnear, etc.
