“Traditional" (Western) theatre focuses on the relationship between the playwright and the director. Devised theatre is a reaction to the dominant ideology; it is ensemble-created original work. A group of artists collaborate and create a play with no script and, sometimes, no initial theme or message. They use various different art forms as well as interviews and narratives to create a theatrical experience.
