Today's Piano Puzzler

This week's contestant is Emilio Gandara from San Juan, Puerto Rico.  It'll start out sounding like you should get the song, but it's well hidden.  However, there is one point -- I won't say where -- where to me it becomes blatantly clear.  I had a guess with the composer style, but was far off.  But I knew when I heard who it was it would make complete sense.  And it does. At least the contestant got it immediately.  So, clearly it's very guessable.
