Beethoven's piano sonata No 14- presto agitato. I actually took this bit of the sonata and uploaded it because i haven't seen this part of the performance alone in other videos. I believe it is performed by Paul Pitman, heres the link for the original full sonata : http://www.youtube.com/watch?v=4Tr0otuiQuU&feature=my_liked_videos&list=LLofjC63JK2z9F-cgkYzqnOA
