I think there's an interest right now in the performance aspect of artworks, instead of just hanging things on walls. We're in a moment when a lot of younger artists are looking at work from the '60s and '70s - they are looking at the pieces by Marina Abramovic or Vito Acconci. These pieces have a time element. They were performed live. To perform them again now isn't simply an homage, because it's a different audience, a different moment.
