I was watching youtube the other night and saw these videos. This one is for @doge. Tiffany is a bit awkward at the speaking part but kills the piano playing but the upshot is she played a Rachmaninoff piece with a famous cellist using period instruments and then the same piece with modern equipment. It is all explained in the video. You can fast forward to the interesting parts. I thought you might enjoy it and see if you can hear the difference.
For @tmonk , I found a performance by a woman of the Military Polonaise that was just flawless. She just slays this. I could only dream about playing it that well. I would fly to Europe for a masters class from her....
