My own shtick is often not looking too deep, and I will employ it again here. :) I still think a lot of indie is "necessity as virtue" -- people do the best they can with the voices they have, and part of the "wall" that was broken through by punk was vocal stylings as well. Listeners' ears were prepared to accept virtually anything from vocalists by that point. And to that extent indie is not giving a shit too, not just being humble/faux-humble. "This is as well as I can sing and that's okay."

Where does Lou Reed fit into all this? Admittedly highly stylized, but at the same time I think there's some link there.
