This year’s spring production from the CAP/Plaza de la Raza Youth Theater Program is a new drama written by Culture Clash member Herbert Siguenza and staged with a cast of 45 high school students. An adaptation of Soldado Razo -- the classic work by Luis Valdez that was first performed in 1971 in connection with the Chicano Moratorium antiwar movement -- Private Eddie U.S.A. takes a hard look at the impact of the war in Iraq as mourners at a funeral enact scenes from a fallen soldier’s life.
