Since 1992, the theater director, choreographer, and activist Ping Chong has been shining a light on issues of gender, class, race, and religion to educate communities all over the world. In honor of the 20th anniversary of his performance series, La MaMa presents Ping Chong + Company’s Undesirable Elements Festival: Real People. Real Stories. Real Theater, a selection of the best works from the nearly 50 created over the past two decades that take interviews with real people and turn them into moving, thought-provoking theater. On the program are Cry for Peace: Voices From the Congo, Secret Survivors (featuring adult survivors of child sexual abuse), and Inside/Out (which concerns the disability community). Plus, catch panel discussions, live streams of performances, and the screening of a new documentary Secret Survivors: Using Theater to Break the Silence.

Mondays-Sundays, 8 p.m. Starts: Oct. 18. Continues through Nov. 4, 2012
