You have done a technically amazing job with this piece. My only suggestion is that perhaps you play with a bit more pedal and give it a darker sound, except for the middle part.
The middle part has beautiful voicing and the playing is passionate.
The return to the beginning section is paced in a suspenseful and effective manner
The recap seems to have a bit of a thicker sound. I think you should try for that sound from the start of the piece. It sounds as though the notes are glued together,
more theatrical in a way.
It could also be that from the middle section on you play with greater use of the big muscles and put more weight into the keys. That coupled with thicker pedaling makes a truly remarquable sound.
Keep up the great work.
I think we both must share a bigger, more powerful view of this piece, than the lighter version that the composer plays. Thanks for your reply. I still have work to do here.
