This California cowboy and former polyrhythmic rock drummer (the Holy Modal Rounders) became the dramatic voice of his generation and was perhaps the most influential playwrights for the decades of the 1970’s and the 1980’s. A playwright, actor, and film director, he was associated with many films, including the original “The Right Stuff” and the lead in the filmed version of his own play, “Fool for Love.” His plays include Curse of the Starving Class, Buried Child, True West, The Tooth of Crime, and A Lie of the Mind. Who was this brilliant polymath?
