Disc is really growing on me. There is truly no one else on Earth like him in the public eye. His extreme nature makes for compelling art, and there is a place for that in the world b/c most art is fluffy obfuscation.
Having done a great deal of studio recording, I can relate to the use of the black curtain. Vocal performance can be a very very intimate thing (even more so than being on stage, I think) and some of us look pretty damn goofy when we're emoting deeply. One should have the freedom to be fully expressive without several studio engineers watching like emotion hawks, even if unintentional.
