Hour 1: The recent high-profile detainment and release of artist Ai Weiwei brought the Chinese art scene into the world’s eye. What is the current status of Weiwei and other artists in China? We’ll spend this hour with Nasher Sculpture Center Director Jeremy Strick and Melissa Chiu, Director of the Asia Society Museum in New York. They’ll deliver the talk “China: Artists Behind the Wall” this evening at the Nasher.
