Founded in 1985, Critical Mass Performance Group is a Los Angeles-based, collaborative ensemble. Known for category-busting new works, exuberant theatricality, and electrifying collisions of ideas, CMPG was named 2013's Best Theatre Company by the LA Weekly. We believe that sharing stories sows the seeds of empathy, in order to imagine and manifest a just, equitable, and peaceful future. 

About Us:

We are passionately committed to theatrical inventiveness in which movement, image and text have equal weight in telling the story, to discover the most theatrical and poetic expressions that work their way through the audience's nerves.  We are compelled by surprising collisions of ideas, by material which reflects humanity’s struggle to navigate a difficult world, and by untold aspects of these stories and how they relate to the American experience.  We aim for work that is historically aware, politically charged, deeply felt, rigorous, accessible, and wildly entertaining.  We work for as long as it takes to finish a piece, and we perform the piece at various stages of development.


In 2016 CMPG premiered AMERYKA, which was honored with awards for Production of the Year and Best Ensemble by Stage Raw, nominated for 7 Ovation Awards, including Best New Play, Production, and Ensemble, and nominated for Best Ensemble by LA Drama Critics Circle.  ALCESTIS (2013) was developed at the Getty Villa Theatre Lab and premiered at Theatre @ Boston Court in Pasadena. Named in 10 Best Plays by LA Weekly, the production won a Best Adaptation Award from the LA Drama Critics Circle, the LA Weekly, and Arts In LA, and was nominated for best direction, sound/score, production design, choreography. APOLLO (2002-2009), an epic trilogy exploring the US space program, its relationship with Nazi rocket scientists, and the surprising intersection with the Civil Rights Movement, premiered Parts 1 & 2 at the Kirk Douglas Theatre in 2005, won a Garland Award for Best New Play, and was named in the Top 10 Plays by LA Alternative Press. Part 3 premiered with the full trilogy at Portland Center Stage (Oregon) in 2009. THE AKHMATOVA PROJECT (2000), a movement-theatre piece inspired by the life and work of Russian poet Anna Akhmatova, was named one of the 10 Best Productions by the LA Times, received four LA Weekly Award nominations including Best Production, and won for Best Choreography.
