1. A work of art, poetry, music, or literature which transcends mere whining about trivial problems, but achieves such dark majesty, that all who experience the work are affected by it.
E.g. Catcher In The Rye by J.D Salinger, Interview with a Vampire by Anne Rice, Hawthorne Heights music, etc.
That Emo kid's art project is an Angst-erpiece! It makes me feel all dark inside!
