Today's Piano Puzzler

This week's contestant is Allison Toltz from Montreal, Canada. This is one that on every level I felt like I should get both the hidden song and composer style -- but didn't.  But sort of did.  It's a well-known composer, but not as well-known as the most-famous of this style, and I didn't get the specific person.  As for the song, it reminded me of one particular song, and I thought it was that, but not enough.  And...that's what it turned out to be!  So, if you play along and have a guess, don't veer off it.  You might well be right.
