I don't know this piece, but IMHO you play this transcription with a combination of Old World charm and delicacy in the slower parts and bravura and nobility in the more expansive passages. Great leggiero, portato octaves! That's no mean feat. Any of my nitpicks would be down to more specific details (little points of polish that struck me as a listener, not knowing the piece). A few comments:
1. A couple of the more contrapuntal passages seemed as though they could be slightly crisper/more even, notably near the beginning.
2. The trills in that one part were nice and clear, but seemed a bit prominent against the bass, which seems to be carrying the tune more in that one place. It goes without saying that such passages (which seem to appear a lot in Liszt too) can be a bitch to sustain, so this is pretty picky.
3. There were one or two places nearer the end (where it breaks out a bit) where you seem to slightly struggle with the tempo, though maybe some retention was intended.
4. Regarding the sound, I think it's nicely balanced overall, but to my ears it seems just a tad brittle in the upper registers. Could be my speakers though, which tend to sound that way.
These are very nitpicky things, though. One thing I'm very impressed by is your dynamics and sense of balance. Regarding the piece, I think you make it about as interesting as anybody could. It seems rather meandering to me, very much in the manner of Thalberg's solo works, not lighting a candle to those by Liszt or Rachmaninov. Speaking of which, since you're a transcriptions guy, do you plan to do any of the Rachmaninoff? IMHO those are the very greatest of all transcriptions, great creations in themselves. Given your impressive chordal technique I'd be curious to hear your performance of the Liebesfreud
Again, great style on this Traviata transcription. A pleasure to listen to your playing as always.
