I know that it has been a while since you posted these, but I am just getting back on PS and working on fulfilling my "duties".
I loved both performances. This Ballade is one of my favorites, and I agree that it is too overlooked. I think that the key should be given as "in F maj and everything but F".
It is so totally manic/depressive, schizophrenic, bipolar. I had worked on this years ago, even had it memorized, but I had to give it up because it was playing to some "demons" inside me at the time.
Anyway, I think that you pulled it off admirably. It is a monster and you did tame it. Oh yeah, I could probably follow along with the score and find some points, but others have probably already made the suggestions that I would make. I appreciated the performance and all the hard work that you have had to do to perform it.
For some reason I am not familiar with his Ecossaises. I enjoyed your performance of these also. It reminded me a bit of a 4/4 version of some of his waltzes (the "Minute Waltz" comes to mind) -- sort of a stylized two-step to be played between the waltzes. Your performance was very convincing. If there are any issues between your performance and the score, they didn't mar the performance. Interestingly, Chopin actually gave a tacit approval for tastefully
deviating from his written intentions. Not only do we know that there are variants in his own hand all over the place, I am reminded of the remark that he made to one of his better students: (I probably am paraphrasing more than quoting) "That is not the way that I was thinking when I wrote it, but your interpretation is good. Continue playing it that way."
All in all, good job.
