What a wonderful performance. Everybody should go listen to this right now. I like your interpretation; it's joyful, yes, and it's got a nice conversational quality to it that seems very fresh and appealing. Like the hands are two characters trading ideas and considering what the other one has to offer. Your articulations are very crisp and things like fast repeated notes are quite impressive.
Thank you for these kind comments ! Yes, one of the qualities of these variations lies in the symetrical role of both hands, and in their constant dialogue.
5:10-5:20 -- something odd happened here, maybe the hands got a bit disconnected from each other? On the other hand, after this point the music began to sound even more open and free. I must say that this is the kind of thing that would never bother me as an audience member listening to a live performance since it was a momentary problem and things got better afterward. (Was this a single take?)
Actually this version is a collage of two takes. Expert ears will notice easily where the cuts have been made, since I am a less than average sound engineer... As for the variation you mention, it is simply one of the most difficult ones, and my two hands tend to fight with each other instead of developing a good collaboration
The variation beginning at 11:12 might be my favorite -- the phrasing on those multiple lines composed of alternating notes is so nice, thoughtful and playful, especially in the second half.
(Now that you've put forward all this effort and created such a beautiful interpretation, you're consigning it to the dungeon???)
I just meant that, due to limited time to spend every day on my piano, I tend to stop playing a piece once I have recorded it (except if I have opportunities to play it for a public, which should happen hopefully next summer for this one...
