Hate to link to YouTube because past posts have turned into mortuaries of dead links as this corporation or that petulant artist has demanded that their crappy grainy minuscule scraps of content be removed, but...
Was talking to a friend last night about Gilbert & George and their start in the '70s as "living sculptures," before they became big gallery-supported purveyors of large multi-pane conceptual photographs.
Found a YouTube excerpt from a documentary about those early years here.
