If it’s someone who can play ANY PIECE, and I am not acting delusional… It is by the hands of Valentina Lisitsa.
She is one of the most technical, expressive, and widely recognized pianists today. Her use of technique in her playing with her emotion, she is probably THE best pianist alive today. She can play anything with the ease of simplicity, and can do it pretty damn good.
Watch her play “Little Red Riding Hood” by Rachmaninoff.
You will be amazed.
