I am addicted to the Goldbergvariations! Besides the wonderful Gould recordings, there is the new one with Perahia to mention. I did like them really. In last time it is too soft for me

. I don't know the one with Ashkenazy. *one more CD to look for is on my list*
Other most loved pieces of me: Oh there are so many. Beethoven sonatas, Mozart c-minor sonata and F-major KV 332 and B-major KV 333. His d-minor fantasie is awesome.
I do love the first partita most, Welltempered clavier, i couldnt decide one fugue or prelude.
C.Ph.E. Bach sonatas i really enjoy.
Rameau i adore, and play much in last time.
Haydn sonatas shouldnt be forgot, and then this romantic pieces like Rachmaninov, especially his preludes, and also Schubert sonatas. He is only wonderful. Besides his last three sonatas there are so many to look for. Specials are always his minor sonatas. (I played his a-minor sonata not long ago)
Schumann is ok, but not my best loved. Mendelssohn did write charming youth pieces for piano, and later on great fugues.
So many to mention....
