It is definately worth exploring most of his music. op 15 and op 76 etudes are pretty amazing also. The twelve etudes in minor keys are downright wild requiring explosive virtuosity almost constantly. Get the recording of these etudes by Jack Gibbons to see what I mean. For other pieces try Marc Andre Hamelin. Alkan is awesome to hear and to play (or attempt)
Yeah I don't think Hamelin is a good pianist myself.
The solo concerto is awesome! I especially like when the melody comes back in the "A tempo Con Brio" section, and all the repeated notes sound very accurately like the strings of an orchestra.....it's soooo cool. That is defintely a piece that amazes the heck out of me just from the awesome variety of sounds you're able to produce from a piano!
I was listening to the piece today and I was just thinking that very thought!!
