Theatre of the Sphere is Luis Valdezs exploration of the principles that underlie his innovations as a playwright, teacher, and theatrical innovator. He discusses the unique aesthetic, more than five decades in the making, that defines the work of his group El Teatro Campesinofrom shows staged on the backs of flatbed trucks by the participants in the Delano Grape Strike of the 1960s to international megahits like Zoot Suit.

Opening with a history of El Teatro Campesino, rich with Valdezs insights and remembrances, the books first part provides context for the development of the Theatre of the Sphere acting method. The second part delivers the conceptual framework for Valdezs acting theory and practice, situating it in Mayan mathematics and metaphysics. The third part of the book applies this methodology to describe the "viente pasos," the 20-element exercise sequence that comprises the core practice of El Teatro Campesinostrengthening the body, balance, precision, and flexibility but also leadership, collaboration, observation, vulnerability, trust, and expression of passion; of consciousness of time, place, self, community, language, and belief; of honour, faith, morality, and commitment. The book concludes with the full text of Valdezs poem, "El Buen Actor/El Mal Actor," and a comprehensive bibliography for further study.

This is a vital and indispensable text for todays actor, as well as scholars and students of contemporary theatre, American and Chicano performance, and the process of theatre-making, actor training, and community performance.
