Suggestions for Classical Piano "works of merit"

Following a disc of Beethoven Piano Sonatas by Anne Oland I just put on a CD from "Shumann Piano Works" played by Wilhelm Kempff. What an extraordinary contrast in both content and playing. Wilhelms intense sensitivity to the moment by moment transitions in Schumanns lyrical and personal "Scenes from Childhood" and "Fantasies" is starkly,and beneficially contrasted,following the Beethoven pieces, and reveals a true master plumbing the full potential of the pieces & piano. This is from a 4CD Deutsche Grammaphone compilation from 1967 to 1975; (Stereo 471 312-2), recordings that I very highly recommend to afficianados and new listeners as well. (The recording quality is excellent on my Spectral/MIT system.) I would enjoy and appreciate hearing of other fine collections and any feedback on the Schumann.
