"Tribes"

Mare Winningham and Jeff Perry talk about their roles in the 2010 Olivier Award-nominated play “Tribes,” which follows Billy, a deaf man raised inside his parents’ fiercely idiosyncratic and unrepentantly politically incorrect home. Then he meets Sylvia, a young woman on the brink of deafness, and he finally understands what it means to be understood. “Tribes” is playing at the Barrow Street Theatre through September 2.
