'Untitled' is a time machine that can transport you to 1992, an edgy moment when the art world was crumbling, money was scarce, and artists like Tiravanija were in the nascent stages of combining Happenings, performance art, John Cage, Joseph Beuys, and the do-it-yourself ethos of punk. Meanwhile, a new art world was coming into being.

Many art-worlders have an if-you-say-so approach to art: Everyone is so scared of missing out on the next hot artist that it's never clear whether people are liking work because they like it or because other people do. Everyone is keeping up with the Joneses, and there are more Joneses than ever.

A sad fact of life lately at the Museum of Modern Art is that when it comes to group shows of contemporary painting from the collection, the bar has been set pretty low.

The alchemy of good curating amounts to this: Sometimes, placing one work of art near another makes one plus one equal three. Two artworks arranged alchemically leave each intact, transform both, and create a third thing.

Everyone goes to the same exhibitions and the same parties, stays in the same handful of hotels, eats at the same no-star restaurants, and has almost the same opinions. I adore the art world, but this is copycat behavior in a sphere that prides itself on independent thinking.
