Added a bunch of "citation needed" to unsourced statements. I'd say we need to work those through either by finding reliable sources or by removing them. There are some statements that I find dubious or obviously untrue, but i left them in and tagged them for discussion. POV language in a few parts, too.
I also removed the "representative artists" section or whatever it was called since it didn't seem representative to me at all, there were no sources cited to back that claim up, and because it was basically just a list of artists like the one that was removed from the old article after some discussion. I doubt any of us will ever be able to make an unbiased, concise and relevant list of representative artists, even if we combined our efforts. Also name dropping lists are booooring and don't really belong on wikipedia.
