Very fine playing, indeed. I, personally prefer it a bit slower and at a more steady tempo. But your interpretation was utterly convincing and I enjoyed it very much.
very nice. the main theme of this piece always reminds me of the klagende gesang from Beethoven op 110, which of course in turn reminds me of the St Matthew Passion. I guess "musical borrowing" was alive and well then as it is now. anyway, you played quite well!
