'Beyond Broadway' denotes the geographical and spiritual challenges to prevailing standards which so fragmented the theatre of the 1960s in particular. Following his analysis of the Off-Broadway and Off-Off Broadway playwrights and theatres, Dr Bigsby separates the period into four main areas: performance theatre (including the Living Theatre and the Performance Group); the conjunction of dance, music and painting with drama in the 'theatre of images'; two successful contemporary playwrights, Sam Shepard and David Mamet; and finally the committed theatre exemplified in, for example, the San Francisco Mime Troupe, Chicano, black and women's theatre.
