Dan Graham quotes:

Warhol and other Pop artists had brought the art religion of art for art's sake to an end. If art was only business, then rock expressed that transcendental, religious yearning for communal, nonmarket esthetic feeling that official art denied. For a time during the seventies, rock culture became the religion of the avant-garde art world.

A [spatial, temporal] work had only to be exhibited in a gallery and then written about and reproduced as a photograph in an art magazine. Then this record of the no longer extant installation, along with accretions of information after the fact, became the basis for its fame, and to a large extent its economic value.

In fact I always disliked conceptual art, because my work is about anarchistic humor.
