South Coast Repertory presents Blue Door, by Tanya Barfield. The grand tradition of oral history comes alive onstage, in a groundbreaking production sparked by abundant humor and woven through with original songs. A mathematics professor, sleepless during a night of personal and professional crisis, is visted by his ancestors. As four generations -- from slavery through Black Power to the halls of academia -- probe and challenge with their disturbing stories, he begins to understand what it means to be black, then and now. Leah C. Gardiner directs. Winner of the 2003 Helen Merrill Award for Emerging Playwrights, Tanya Barfield was named by Ms. Magazine "One of the 21 Young Women to Watch for in the 21st Century."
