To me, one of the most interesting moment of Venice Architecture Biennale was the 3 days long marathon interviews by Hand Ulrich Obrist. He basically interviewed all the Biennale participants. The dialogue were taking place in the middle of the main exhibition hall, the Giardini, were a t.v studio was set up. So the crowd was watching all the interviews both live and on lcd screen. Between an installation and a press check-point, a media monster.
Here are some of the interviews, posted on youtube.
