Bill Evans (the pianist).
I own virtually all of his "classic" Riverside trio dates, plus a smattering of the Verve, Fantasy and other releases, but more out of a vague sense of obligation than because I especially enjoy them, or listen to them all that frequently, actually. Like, I should own these because the day will come when I do appreciate them. Only that day has not quite come.
Ultimately, I prefer his sideman work with George Russell just about more than anything else in his discography... back when he was far more under the spell of Tristano than [insert reference of your choice here]. And I have to say I find the coked-out energy of the late 70's - early 80's trios much more compelling than the the LaFaro trios. But my listening of the former has still been fairly superficial.
