As I have alluded to before, the OP has an agenda. Do I, regarding my Original Performance video? Yes, I do.
And, as I have said so before, this was to promote the manner in which the great composer/pianists of the 18th, 19th, and early 20th centuries originally played and also taught this "great" music.
What I do not do is to post a ridiculous question about learning a piece in 2-3 days. And, since no one asked: Rubenstein, Gieseking, and Backhaus (among others) had the ability to go into a studio in the morning, sight read the scores and have a finished recorded product by the end of the day.
Do you think that a man, not a god (Rubenstein) effectuated over 200 recording sessions, with "NO PIANO TEACHER." For the record, under the tuteladge of Joseph Joachim (violinist), he had formal instruction under a man named Barth. And, this was terminated after the age of 16.
So, I am stupid. How did this great musician, who never had a lesson as an adult make all of these great recordings? Duh: he sight read them, just like Gieseking, and Backhaus (among others) did.
Accordingly, Uchida blew the whistle on Andres Schiff in an interview some time ago, alleging the same thing.
So, has the OP accomplished his/her goal? Yes, they have, and I am done this garbage.
