Both Bartok and Rachmaninoff are fine composers as well as pianists, and it's well worth checking out the music of these young upstarts...

I should probably add a mention to Dmitry Shostakovich's "Sonata for viola and piano, op.147" and the 3rd Movement: "In Memory of the Great Beethoven: Adagio".
Not a Beethoven work obviously, but apparently he references the Moonlight Sonata in it.
Did "Shosty" play the Grosse Fuge to relax after work?
