I really love the jazz/classical fusion (especially with Bach-type stuff), so I looked around on the net and found out about Jacques Loussier. I know I've heard some of his stuff before, but this is the first time I've actually looked it up and seriously gotten into it.
Great bass playing, too! I love that kind of clean bass playing.

Check out Invention No. 8 in F major, Air on a G String, and Prelude and Fugue No. 2 in C Minor... those are my favorites.
