Excellent work on this sonata. In general, you handle the difficulties quite deftly. Generally clear passage playing, excellent dynamics, and good pacing. I also think you capture Beethoven's quintessential energy and ebullience well. The flaws I find very minor, though I did note a few things (after all, you asked for nitpicks
)
Movement 1: The thirds at the beginning could be just a tad clearer and more even, though I know how difficult that is. Excellent voicing in the ensuing polyphonic passage. Great mordant precision on those broken octaves! The left hand could be a little clearer in the Alberti basses (and maybe a tad less pedal). Well-planned phrasing and dynamics throughout. The only really problematic passage for me are the broken sixths in the development, which seemed a bit uneven in sound (I couldn't hear many of the notes) and awash in pedal. It's tough to keep those going though, to be sure. The cadenza-like coda is fantastic! The timing, clarity, pedaling, and dynamics all seem just right.
Movement 2: Very well and expressively played. I would recommend perhaps experimenting even more with phrasing and just a bit of rubato here. It sounds just slightly straight-laced to my ears. You follow the score well but there are a few places you could have taken an initiative beyond the printed markings and done more IMO. Take the beginning. I would hear more of an accent and dimin. for the first quavers and then a crescendo and release of tension in the following two. Maybe your tempo is just slightly on the slow side to accomplish that, though I know these are very much matters of taste. Some of your balance against the thirty-second accompaniments could be a bit more pronounced perhaps. One other tiny detail that seemed odd to me is the turns at the end, which you play on the beat but Beethoven has indicated as between the beats. Could be a difference in scores though.
Movement 3: Good energy overall. Maybe could use a bit more polish in places. This is the only movement where it became a bit of a distraction for me since the slips were in obvious and not particularly difficult places. But hey it's a live performance, so no big deal. Is it just me or did you play the triplet trio faster. I think that can work, and I find your dynamic squalls and accelerandos here exciting. The only problem was that when you came back to the scherzo reprise, your tempo may have been faster than the one you started out with, and I'm not sure that's kosher.
Movement 4: Really excellent playing throughout. The lightness and insistence of those triads to start is really phenomenal (I also like your headlong plunge to the top -- very exciting). Good pedalling too, creates a nice fluid effect in the 16ths. Maybe the passage in the lefthand with the thirds was a little weak, but I know with that leap it's damn difficult. Great octaves. You obviously must have very flexible wrists. One small detail I noted is the lefthand trill toward the end seemed notably weaker than the righthand ones. A few obvious rushings in places too but that actually contributed to the excitement in a way.
Despite my nitpicks (which are really quite inconsequential but I like to do it all the same
), really congratulations are in order here. This is overall fabulous playing, and made all the better by its exciting delivery in a live venue.
