Using a critical race theory (CRT) framework, this article compares the playwriting methods of the Chicano--Latino theater trio, Culture Clash, to a counterstorytelling methodology. The author uncovers the tenets of a critical race theater in the trio's site-specific ethnographic play, "Radio Mambo: Culture Clash Invades Miami". He argues that this performance art consciously challenges social and racial injustice by illuminating the lives and histories of diverse urban communities. Grounded in a Chicana/o "teatro rasquache" aesthetic, Culture Clash's theatrical ethnographies speak to a broad array of audiences about race, class, culture, gender, and identity.
