Yes, I agree, that kind of thing is relatively infrequent, even in today's art world. A multi-media painting of a black Madonna using, among other things, elephant dung, stirred up some controversy in New York a few years back. Nudity is still an element in some performance art, as in a notorious installation at the Guggenheim not long ago with live nude models. And the 'shock and outrage' idea surfaces in abstract music from time to time, though perhaps without elephant dung or nudity. But whatever the merit or lack thereof of this material, it is a small niche in the art world. Yet, some 'critics' jump all over it to make blanket value judgments on all modern and contemporary art.Are there really any young composers working today whose main aim is to shock ? I wish there were! But I can't think of anyone off the top of my head. "Pussy" Riot shock, but it's certainly not their main aim. Lachenmann wanted to shock with Pression maybe, but that was a brief phase in his work and anyway, it was a long long time ago.
