Spring Awakening and the issues it discusses.
I love this musical for three reasons.
1) The music
2) The intensity of the emotion
3) The topics it brings up.

Now, number three might seem a bit odd. But it's important. Spring Awakening deals with issues like abuse, sex, and suicide. All set in late 19th century Germany. I think it's important to address issues like these, and what better way to do so than through a medium people can be moved by?

This rock musical is phenomenal and emotional and I can't really say much else right now, because I have to go shower xD

As the Italians say, "Art is long; Life is short."

Arivaderci!
