Hi Steve, nice to hear your recording. Well, your opening phrase is very passionate and believable. You like the ff and the faster tempo perhaps because of the sense of energy you want to bring to the performance. I personally think it is possible to achieve an energetic flow even at slower tempos, and yours is the fastest I have listened to. I don't think it
needs to go this fast to maintain a sense of life. Have you tried it slower just to compare ?
Along the lines of maintaining a sense of life, you may want to breathe a little more

. Although there is only one riten. in the piece, even if you do not slow down at all toward the end of the other two phrases, a breath would be nice. A chance for us as the listener to clean our palletes a little, and take a sip of red wine...
You have obvious thoughts on dynamics and express those clearly, however, in the last phrase the tone became less clear than it could be, even at pp. Perhaps you came down in volume so much within the second phrase, you had little place to go from there.
I am betting that you have listened to Argerich, as she states the last chord quiet loudly, as you have also decided on. I find that interesting in general because I don't recall seeing an edition that actually has anything but "p" there. I will admit though, I have thought "well, if Argerich did it, why can't I ?". I guess we decide. My only thoughts about that cresc. right before the last chord is that it seems you go beyond the level of dynamics you have established for that phrase. I know it needs to get louder, but perhaps it is more the tone and the intention of your chords at that point, they don't fit within the phrase. They are a little harsher and more pointed. Perhaps you want something that sounds like it does not fit exactly there, but if that is not the case, you may want to adjust your overall phrasing a bit.
Lastly, there is something I am finding funny about this piece and its various performers and editors. In measure 3, beat four, that C chord is written as Major as the E was naturaled on beat 2. However, Argerich plays Eb (making it c minor) as well as the recording that PS has posted next to the score. Pollini, on the other hand, does not. He plays E natural, making it a C major chord. In the Schirmer edition, it stays E natural, while in another edition I have (Augener's (?)) it also is E natural, but somebody has written in a flat over that note as though they were advised by some authority to change back there, but the editor had not caught it (I bought this one used so somebody else put it there). In the PS edition, somebody has hand-written in a natural sign, so I suppose that opposed to the recording, somebody here feels it should be E natural. I believe the sheetmusicarchive edition actually has printed an Eb, though. So, it's a mystery to me.
In any event, you played an Eb, and according to most editions (though not all recordings) it is an E natural, making it C Major (as I already said

).
How long have you been working on this piece ? I would love to hear this again in a little while. Keep up the good work
