Hell is a real possibility for all of us. It's not a happy thought, but it's an appropriate introduction to today's Music Monday selection, our last musical offering before Ash Wednesday. It's not really sacred music, but it is very relevant indeed to the Lenten themes of sin, repentance (or not), and damnation. This is the finale* of Mozart's opera Don Giovanni (a.k.a. Don Juan), one of the most powerful scenes in the history of musical drama.
