Mussorgsky's Night on Bald Mountain
Kind of appropriate for a discussion about government-run health care, I think. My only problem right now is trying to figure out if that bell at the end symbolizes our victory over the tyrants, or if they symbolize the church bell ringing at our funeral.
It's one or the other.
As an aside, I think this is one of the best examples of story-telling through music I have ever heard. If you can't see the back-and-forth of the elements clashing with each other as you listen to this, then you've probably been exposed to too much modern crap, laughingly called "music".
