You should go to google and look for something referring to pianists. You could probably find some good classical music, you could probably try iTunes or maybe a local music store.
I don't know much about pianists (typical piano's) but janne warman from children of bodom was rated number one keyboardist in the world in a famous music mag I was reading (can't recall the name I'll try and find it later)
I agree with Deadzone u looking for someting a little Advanced cant go wrong with Children of Bodom if u got Keyboard and also the Band Warman is pretty good keyboards in it chekc that out
