Theater, viewing and participating in performances, is an ancient yet vital cultural force. Theater — particularly its "illegitimate" forms — can punctuate the ordinary and evoke new and unexpected experiences. It can introduce new, temporary realities in which the self is momentarily forgotten and submerged. Anybody can practice Illegitimate Theater that causes ripples in the everyday stream of life. It can be used to provoke emotional reactions, discussion or reflection. It can even help foster social change and the democratization of culture.
