Book excerpt: Jana Sanskriti is internationally recognised as the most iconic post-Boalian Theatre of the Oppressed operation in the world today. This fully illustrated book by the Bengali company's founder and artistic director Sanjoy Ganguly, edited by Ralph Yarrow, collects and explains their programme of workshop exercises, placing them in the context of their social and activist work. A set of interviews with Ganguly complements these practical sequences, drawing in topics such as the role of the joker, the nature of development, participation and agency, aesthetics as transformation, and Theatre of the Oppressed in the context of a market economy.
