DURHAM, N.C. – For seven weeks this summer, an experimental collective of artists and thinkers from Duke University’s Laboratory for Social Choreography will bring together hundreds of people in the Benaki Museum in Athens, Greece, in an exhibit unlike any other. He knows that it sounds strange at first, but Laboratory for Social Choreography director, Duke professor and artist Michael Kliën says that imagining alternatives is the only sane response to our current moment, in which the seemingly inexorable systems that have produced climate change and extreme wealth disparities have many citizens feeling hopeless and stuck.
