Jim Lasko of Redmoon Theater of Chicago gave this talk at My City's Still Breathing, a symposium examining the intersections of the city and art. In it, he talks about how performance/spectacle is necessary to break habits of perception. And I'm all about breaking habits of perception.
The symposium happened this past November in Winnepeg, but the Canadian government has facilitated the hosting of videos and audio from the conference on this nifty website. Well played, Manitoba.
