The new approaches to playwriting and performance pioneered by Eugene O'Neill, Susan Glaspell, and the Provincetown Players gave theater a new cachet early in the century through the possibilities offered by naturalism and expressionism. Overtly political content took the stage in the protest plays of Clifford Odets during the Great Depression though in general a more insular realism proved the dominant style, albeit one interrupted by recurring periods of experimentalism. Key moments and artists who defined the later half of the twentieth-century are illuminated through in-depth essays on the scathing indictments of the American dream put forward by Arthur Miller, Tennessee Williams, and Edward Albee; the impact of the countercultural, mixed-race musical Hair; the complex nature of David Mamet's social critique; the energy of experimental, off-Broadway theater; the importance of place and memory in August Wilson's works; and the acute anxiety over the AIDS crisis during the Regan eighties as presented in Angels in America. The volume will conclude with a consideration of what lies ahead for the nation's drama, focusing on the pivotal work of leading lights such as Sarah Ruhl and Suzan Lori-Parks.
