Thanks for the responses, at the moment I don´t have many recent recordings, this is one of the best I have. About the sheetmusic, this score posted here is not very good. when I studied the piece I used my own ears. Sheet music can help you a little bit, but there are no good versions of Horowitz and Volodos transcriptions.
Thank you for posting the score. You didn't have a score at all? When I browsed through the score posted above, I noticed that it seemed to lack at least a passage that you played at the very end of the piece.
Thanks for all the responses The first time I studied the piece I did use a score, but noticed that there were so many mistakes. So I listened to Volodos version (on Sony "live at Carnegie Hall") and played his version. That explains also the lack of the last passage in the Horowitz score. anyway, Thank you all
