Today's Piano Puzzler

This week's contestant is Ben Fowler from Helena, Montana. It took me about a minute to find the hidden song, but I did.  At first I thought it was something else, but that particularly song would have been too obscure.  And it was quite well-hidden, however there was one passage that finally leaped out clearly to me.  It gave an initial hard time to the contestant, but he got the composer style immediately, which was impressive because the composer, while famous, is significantly less well-known than the especially-famous names  And no, I didn't get it.
