This week: Half Off. Why is attendance at the Art Gallery of Alberta only half of what it was when the new building opened, and what can they do about it? We speak with Edmonton City Councillor Andrew Knack why he voted against funding an experiment with free admission at the gallery. And we’ll talk to Latitude 53’s Todd Janes and Santa Cruz Museum of Art & History’s Nina Simon about what other galleries are trying to get crowds in the door.
