Can someone tell me what this piece is?

I was walking around, waiting for my drum teacher to arrive for my lesson, at a college, and heard someone playing a beautiful piece in his room. I didn't have any way of finding out what the piece was there, so I recorded some of it on my phone so I could examine it later. I've attached the two short recordings I made. Hopefully someone here will be able to figure out the piece for me. Thanks!

That's from Chopin's second sonata in B flat minor op.35, from the first movement.
