Some people don't like the way Valentina Lisitsa plays because they say it's too technical or they think she's just showing off by playing so fast. I think she just has a great natural ability to think of some music and it comes out of her fingers that way. By the way. Parts of Totentanz remind me allot like Radiohead - Paranoid Android for some reason.
People seem to like thinking that this video shows how she's just robotic. Maybe Rachmaninoff was a robot
