That is Carl Vine's Piano Sonata No. 1, the first movement. This piece has become rather overplayed (relative to other pieces in the last 25 years) in recent years, which is both good and bad. Most people, however, don't do that great of a job with it (this girl is sorta just ok). It is good to see a new work get a lot of attention, though. Check out Michael Kieran Harvey's recording of it for an amazing account of it.
