I don't often go to curator or artist walk-throughs of exhibitions. For a critic, it feels like cheating. I want to see shows with my own eyes, making my own mistakes, viewing exhibitions the way most of their audience sees them.

'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.
