@maruey @MisuseCase @BBCRadio4 One of the main points in Epic Theater (Brecht's theater technique) is to emphasize artificiality and constructed nature to make sure the audience and actors are less complacent, and that they go from the work with a new understanding of the world, and as a basis for action. So in Urinetown, you have actors breaking the fourth wall to address the audience, talking about how they are in a musical, etc...
