'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.

Summer is a great time to visit art museums, which offer the refreshing rinse of swimming pools - only instead of cool water, you immerse yourself in art.

Artistic qualities that once seemed undeniable don't seem so now. Sometimes these fluctuations are only fickleness of taste, momentary glitches in an artist's work, or an artist getting ahead of his audience (it took me ten years to catch up to Albert Oehlen). Other times, however, these problems mean there's something wrong with the art.

In the seventies, a group of American artists seized the means not of production but of reproduction. They tore apart visual culture at a time of no money, no market, and no one paying attention except other artists. Vietnam and Watergate had happened; everything in America was being questioned.

The giant white cube is now impeding rather than enhancing the rhythms of art. It preprograms a viewer's journey, shifts the emphasis from process to product, and lacks individuality and openness. It's not that art should be seen only in rutty bombed-out environments, but it should seem alive.
