In the fifth episode of "Barbara London Calling" 2.0, Barbara speaks with Amar Kanwar, an Indian artist whose masterful films and multimedia work explore the politics of power, violence and justice. Born in 1964 in New Delhi, where he is still based, Amar was a researcher for occupational health and safety in the coal mining belt of central India. He turned to art making in 1990, with work that weaves together critical issues of indigenous rights, gender, religious fundamentalism and ecology.
