Not experienced enough to give any critiques but I can tell (well any schmuck can!) that you're still not comfortable with it yet. Needless to say I quite enjoyed your playing. Well done.
While the technique may not be totally perfected, you have a lot of poetry in your playing and in the end, I think that's probably the most important ingredient for a successful performance of the piece. Having heard some of your Chopin Concerto tape, it's obvious that you have the requisite fluency to play this up to whatever standard you desire.
One interpretive comment if I may: I get the feeling that you hadn't established an overarching tempo in your mind before beginning.
It's understandable why there are many slow performances of the Berceuse----after all, the title indicates that it's a lullaby and the music is very persuasive when heard from that perspective. However, did you know that it's one of those pieces the title of which was chosen by someone other than the composer? Lisitsa claims that it was originally written as a series of variations and can therefore accommodate a considerably faster tempo. At the risk of corrupting your ideas about the piece, you might like to listen to Josef Hoffman's, to some, scandalous rendition. I'm quite fond of it. Certainly, trying to imitate him is good for the technique if nothing else and you can always revert to your original conception.
In my previous post I must have unconsciously substituted "serious" for "series." Probably just a typo, but who knows?
There are indeed some beautiful moments in your berceuse. (despite that awful amplitude of the sound. How did you record this? and do you have a troupe following you around to take different angles of your playing? Love it.) I think you know it has to go a bit faster. (That way you won't have to speed up in certain sections like you did!) That's one of the reasons it sounds a little plodding now. Just like you mold many of those phrases in the right hand beautifully, do the same with the ostinato bass. i personally feel it with a resonant base and a slight diminuendo in the last three chords. At any rate, make it sound like a musical phrase. And it should stay basically the same speed throughout. Too many ritardandos. ritardandos that may be alright in themselves, but not here in the berceuse. No, I don't find this piece easy at all. It's so clear and exposed. Almost like MOzart. You hear everything, no matter how much pedal you use. And by the way, you make fine use of the pedal.
Noah, I admire it how fast you learn new pieces! Just a few days ago I heard this little snippet and now you play the whole thing so beautifully! I just love how you feel at home with Chopin's music. I hope to see you in Warsaw in a few years;-)
