I went. I loved it. And Austin, I promise I'm not just pretending in order to show how cool I am.
This isn't particularly typical Shostakovich, not sustained on this scale. He's responding to the surrealist cartoonish nature of the story -- exaggerated reality, everyone always taking things to extremes. I wouldn't want all opera to be like this, but in fact I know of no other opera quite like this. It creates its own world, and it's not especially dissonant: other composers are far more so. But it's certainly colorful and energetic, and the Kentridge production is brilliant.
I can think of opera composers whose work I would flee at intermission (or just not show up for), but I'm very glad I saw The Nose.
