Martin Esslin is the author of seminal critical studies such as The Theatre of the Absurd and Brecht: A Choice of Evils. Covering artists as diverse as Duchamp and Brecht, Busby Berkely and Congreve, Pinter and WC Fields, Esslin's approach is fresh and genuinely inquisitive, examining various prepared positions and testing the jargon. Taking each element of drama - the actor, the setting, the text, the music - and making provocative cross-references to stage and screen, Esslin offers a carefully argued "system" of his own, much fuller and more sensitive than anything that has gone before.
