The art world is molting - some would say melting. Galleries are closing; museums are scaling back.

When people in stadiums do the Wave, it's the group-mind collective organism spontaneously organizing itself to express an emotion, pass time, and reflect the joy of seeing the rhythms of many as one, a visual rhyming or music in which everyone senses where the motion is going.

Put yourself in the position of an up-and-coming artist living in early-sixteenth-century Italy. Now imagine trying to distinguish yourself from the other artists living in your town: Michelangelo, Raphael, Leonardo, or Titian. Is it any wonder that the Italian High Renaissance lasted only 30 years?

There's something pleasing about large, well-lit spaces. I love that dealers are willing to take massive chances in order to give this much room to their artists. Most of all, I love that more galleries showing more art gives more artists a shot.

'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.
