From a YouTube video, concerto attention by Classic fm.
This is how a Ludi (Beethoven) concerto should be played. Quite impressive. As an aside, but related: my take on her thin is that of course she is built that way—we have to know she doesn’t eat. There is no time left after all of the practicing. The pianist is Alice Sara Ott.
To check out the pièce de résistance, tune in to the time mark of 9″30. Enjoy!
