I can hardly believe you posted something by Chopin that has resulted in no comments, yet!
Ondine sounded very good! I'd love to hear you play it on a big piano!
When you say you are performing these, soon, what do you mean by soon? Because, I would say, on the Beethoven, the first movement needs a little deeper exploration and perhaps you might benefit from "dry" practice. In other words, keep your foot off the pedal, and really focus on crisping up the articulation and note values. I mean, in practice, go overboard in a Mozart direction, then bring it back to Beethoven with what you've discovered in fire and emotion during "dry" practice, then add judicious use of the pedal. (I suspect the Avantgrand itself is not helping the situation!
) I really enjoyed your playing of the second movement. (I think you did, too!
) By "focus" issues, do you mean things like paying attention to mapping out the drive to the destination through the second movement? It's a prodigious movement that does need to be carefully "directed" in its momentum to reach that profoundly meaningful conclusion.
Haven't listened to the Chopin, yet, but there are so many others who usually chime in on that, they can have a go...
Anyway, nice work! This has been on my "gotta listen" list since you first posted it, and I'm glad you posted it!!! Keep pressing in and pressing on! You've got great stuff!
