I'd like to never hear Rach 2 or the Rhapsody again. Rach 3 sounds too close to 2 for comfort. If it has to be Rachmaninoff, I would like to see is someone skating to Concerto No.4 (or 1 but we already saw that from Midori) or the Symphonic Dances.I think Michelle used the third movement (if I recall correctly) in her lovely 1998 SP.
I do wish people would branch out with Rachmaninoff. Even the third piano concerto would sound new, though entirely characteristic of him, and it's so close to parallel to the second concerto. There's fabulous stuff from the three symphonies also.
