Like Clark himself, they were not the best-adjusted bunch. His horribly honest photos of his speedfreak friends were collected in his 1971 book, Tulsa, which influenced such photographers as Nan Goldin and Corinne Day.

He's already finished his next one, Ken Park, and it won't be an easy ride. "It's more like my photographs, it's very dark. I don't know if it'll play, but I don't care."
