This article explores Bertolt Brecht’s significance for the most advanced forms of contemporary experimental and avant-garde theater.Brecht is one of the most popular and most-produced playwrights world-wide, and certainly in Germany; however many mainstream productions tend to deprive his work of its radical political and aesthetic edge.Nevertheless, contemporary avant-garde and experimental theaterwould be fundamentally unthinkable without Brecht, and it is particularly indebted to the most radical phase of Brecht’s career, when he and his team were working on learning plays (Lehrstücke) in the late 1920s and early 1930s during the final years of the Weimar Republic. Brecht’s conception of a separation of the elements, of putting mechanisms of power clearly on display, and of creating collective agency that, via script-based theater, tendentially removed power from the hands of writers and directors, are fundamental building blocks of contemporary experimental theater. The article explores such forms and their impact on the basis of experimental work by Robert Wilson, Wanda Golonka, and She She Pop.
