How about a little post-Christmas classical fun?
This is the final movement of the greatest piece of chamber music ever written. On the surface, it's a dance in sonata-rondo format, but under the surface, there are a few demons lurking. The end is like Sissy Spacek reaching up from the grave in the last scene of "Carrie."
See what you mean! LOL! Went all minor-y at the end. :)
