New Orleans artists talk about what they lost and how Katrina will change their work. “The imagery has to change; it’s inevitable. I was always interested in the street life, the poor and what is at the root of that lifestyle. Now my concern is that New Orleans will become a middle-class city. The whole landscape of American art is in the process of upheaval. Between 9/11 and Katrina, I am seeing artists dealing with history. When I was at school we were concerned primarily with form. Now that’s all changed.”
