If there are a few differences - particularly in Canada, the sad spacial absence marking the controversy around Richard Prince's photograph of young Brooke Shields' nude and the unnecessary addition of a room thought-out by so-called genius concept Reena Spaulings but based on a notion articulated better by others fifty years ago (see Nouveau Realist Daniel Spoerri in particular) - both exhibits are a shiny clutter of recognizable works, names, ideas, shows, things, accessories and humor by Andy Warhol, Andy Warhol's disciples (Haring, Basquiat, etc) and Andy Warhol's sons (Hirst, Koons, etc).
This success is obviously tied to the overt and cool 'contentious' issues that are embedded in the show's premise: Brillo Boxes (courtesy Warhol) and a calf in formaldehyde (courtesy Hirst) question art with an 'ironic' regard Mona Lisa incontestably can't. However how does this type of art get to be such a success when similar contentious questions have also been tackled by artists without the clunky use of their penis stuck in La Cicciolina waxed asshole (courtesy Koons)?
When I saw Pop Art at the Tate Modern, the neighboring temporary exhibition was a retrospective, John Baldessari Pure Beauty. After the bustling business and literal heat of the Pop Art rooms, John Baldessari's space was strikingly different - it was empty. Better to contemplate his thoughtful yet biting career of videos, words, canvases, collages and a final installation (see photo above) subtly questioning the nature of our contemporary human condition, the difference of public interest between both shows was a sad nod to what Pierre Bourdieu hoped for: the opening up of museums. Indeed in the 60s this French sociologist observed the exclusion of people lacking a cultural capital, and invited museums to democratize their spaces with better formulated labels, programs, visits, relaxed atmospheres, cheaper entrance fees, etc...
Ideally I'm all about this, I think art can be a powerful force to question our own assumptions on reality. Practically, though, exhibitions that are public successes seem to require the straightforward 'irony' and (at this point) boring 'controverse' of Warhol and this results in people like Jeff Koons and Cosey Fanni Tutti imposing their wet dreams to my face in the name of 'irony', 'mockery' and 'art.'
I believe in Baldessari. (the MET is opening his retrospective next October).
