Carl(os) Roa previews the Power Street Theater Company’s production of “Las Mujeres,” a new play by Erlina Ortiz, running March 9th-17th at West Kensington Ministry. Supported by a pantheon of feminist icons from Latin American history, “Las Mujeres” adapts the unorthodox structure of Caryl Churchill’s 1982 working-woman play, “Top Girls,” to the complexities of contemporary Latinx life.
