The book charts the development of collaboratively-created performances from the 1950s to the present day. Companies discussed include the Living Theatre, Open Theatre, Australian Performing Group, People Show, Teatro Campesino, ThÃ©Ã¢tre de ComplicitÃ©, Legs on the Wall, Forced Entertainment and Third Angel. Against this background of enormous variety, fundamental questions are posed: "What is devised theatre?"; "Why have theatre-makers chosen to devise performances since the 1950s?" and "How has devised performance changed over the last fifty years?"
