Today's Piano Puzzler

This week's contestant is Lauren Cason from Greer, South Carolina.  You're on your own with this one.  It's not a style of music most people are terribly familiar with, I think. I took a stab, but was wrong.  But the contestant and even Fred Child were stumped, too, until a barrel of clues came in. And even at that, Ms. Cason -- a piano teacher -- only threw out a guess and was right.  As for the hidden song, I heard about four that I thought it might be.  I picked one without the greatest confidence, but actually got it.  (For as difficult as it was, there is an amusing method to composer Bruce Adolphe's madness on this one.)  But even Fred said that this was "this is one of the hardest Piano Puzzlers we've had in a while."
