Here is the same piece by British pianist Peter Donohoe and it is my favorite interpretation of it.
Don't you think his agitato is way too slow ?
That's my story and I'm sticking to it!
I have a question: what fingering do you suggest for the agitato sectior? Specifically, in the first measure of that section, should I play all the quarter notes with finger 5, continually shifting my whole hand, or should I play the first with 5, the second two with 4, and fourth with 3 or 4?
