I'm so glad you enjoyed those Liadoff pieces I posted. At first I didn't know quite what to expect from this composer, had never heard the preludes before, but was quickly drawn into them. These pieces are true jewels. I usually make it a point not to listen to other pianists' recordings of pieces I prepare, as I don't want to be influenced. That is, I want to put my own stamp on a piece. I really enjoyed doing these recordings. I was about to move onto to another composer, but was persuaded to do more Liadoff, so I have four more of these preludes in the works now. But I'm not giving out any hints on which ones.
Regarding Berezovsky: When I played the Rachmaninoff revised "Melodie" (posted here), I had heard the Rachmaninoff recording years ago as I have it on CD. Later on I heard the Volodos performance as well. So that was a case where I was already familiar with other recordings, but was still able to do some things differently to make the performance my own--although it could stand some improvements. After I did that recording, I later came across the Berezovsky live recording. I do truly respect him as a pianist. Anyway, he was playing in a large hall in the video, possibly the Salle Pleyel. He came out on stage to play an encore, the revised "Melodie" as it happened. He then spread out the music on the music desk. I wasn't put off by that, as Hamelin sometimes uses sheet music in recital too. And with my inability to memorize anymore, who am I to criticize that?! Well, he was playing and I was keenly interested to see how he would handle the difficult cadenza at the coda. He didn't play it at all!!! He finished the preceding measure, skipped the whole cadenza, and played the final chords in the closing measure. It was like it had been excised. I must say, my jaw dropped open! I thought to myself I certainly couldn't match Volodos' execution of it, but at least I PLAYED the cadenza. Now my jury is out on Berezovsky. Thanks for leaving those two links--I'll check them out. Hopefully he'll redeem himself there.
Best of luck, Hye-Jin in your doctoral program. I'm sure you'll do very well in it. I'm hoping you can still post a recording for us now and then.
