Camille A. Brown has had a marquee year. The choreographer and dancer earned her first Tony nomination for best choreography for “Choir Boy,” making her the first black woman to be nominated for the category in over two decades (Marlies Yearby was nominated for “Rent” in 1996). And this fall, she has two major revivals on the horizon: the Met Opera’s season-opening “Porgy and Bess,” which marks Brown’s debut at the major arts institution, and Ntozake Shange’s influential “For Colored Girls Who Have Considered Suicide/When the Rainbow Is Enuf” at the Public Theater. She’s also choreographing a piece for Alvin Ailey’s upcoming season at City Center and working with director George C. Wolfe on the film adaptation of “Ma Rainey’s Black Bottom.” There are two tours on the horizon, too: for “Once on This Island” and her namesake company, Camille A. Brown and Dancers, for which she continues to dance.
