Today's Piano Puzzler

The contestant this week is Emilio Gondola from Puerto Rico.  As the song starts, you can tell it's one that you should know, but it's just escaping the tip of your your tongue.  It's evocative and well-hidden.  But eventually, there's a passage that should make it eminently clear.  As for the composer style, there are a few people to pick from -- and I didn't get it, but honestly, I should have.  So, it's very gettable, especially if you're far more up on such things than I am, since it's heavily based on a particular piece.
