I appreciate your response yet respectfully disagree (if I am not mistaken as to what precisely you mean).
I am a pianist and I believe that what I have to say is different, exciting and new (is not that the reason why we become pianists in the first place?). Classical music has been blessed by an army of virtuosos, many of them transcendentally talented; as musician's we have tough acts to follow every day, with nearly every piece we play in the standard repertoire.
Now, you say that Rubinstein's act is a tough one to follow. That is a matter of personal opinion! I think following Rachmaninoff's own act or Pletnev's act (which is, in my opinion, a miracle) is even more difficult (please understand that I love Rubinstein; the latter performers take the pedestal in this particular situation, in my opinion).
It is encouraging to know that people still listen to the Appasionata- not only the piece itself- but interpretations by Schnabel, Schiff, Horowitz, and other giants. I will humbly say that they even listen to my own interpretation!
That is what makes music special; the variety of interpretations of one masterwork. There are many winters and lots of snow; I am glad audiences recognize that.
