          Performing Group, People Show, Teatro Campesino, Th矇璽tre de Complicit矇, 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?"
