The hands of Valentina Lisitsa...

...playing Rachmaninoff's Etude Op. 39 No. 6 "Little Red Riding Hood." The video and audio seem to be a few milliseconds out of sync, but there's no CG involved here; she is a well-known professional pianist from Ukraine who has been playing piano since age three. You can view other performances on her YouTube channel.

Here she is playing Rachmaninoff's Second Piano Concerto. I think it's impossible to listen to this piece without thinking of the movie "Brief Encounter."
