The so-called avant-garde theatre in the United States and England is generally a case of new wine in old bottles. The plays of most of the young Anglo-American playwrights do not break new ground. Edward Albee's The Zoo Story, to begin with one of the better known examples, is essentially a realistic psychological melodrama. His Sandbox and The American Dream utilize conventions of the traditional non-realistic theatre. Jack Gelber's The Connection explores a segment of society that has been previously unexplored in the theatre except in terms of melodrama, but the manner of presentation goes back to Pirandello. Jack Richardson brings to The Prodigal a unique intelligence and virtuosity but uses familiar techniques. In England as well, there is vitality within traditional forms. Although John Osborne's observations of the temper of postwar England are vividly realistic, he blazes no new paths of dramaturgy.
