THank you both for the kind comments. The performance was in fact taken from a first round of a piano competition where I passed to semis (playing Prok 3rd concerto) but not to finals. Opinions among jury members were quite divided, especially with regards to Hammerklavier, and divided in an "interesting" way - the three jury members that had actually performed the piece ALL gave me highest praise, while the negative comments mostly came from the four remaining ones that had never studied it, and in one case didn't even want to study it - yes, indeed, there was a jury member who, after we discussed during the feedback session, finally admitted that "perhaps" the problem he had with it was more the piece itself than my very playing of it. How professional...
