“Tribes” at City Theatre

The Pittsburgh Tatler: Nina Raine’s play Tribes builds on the premise that a family is like a tribe, an intensely loyal, often contentious group of people who share a language, rules, rituals, customs, and sense of humor. Families can be quite insular, and, like tribes everywhere, suspicious of the customs, rites, and values of other tribes. So what happens, her play asks, when one member of a family, beloved as he may be, is not only profoundly different, but also begins to let that difference set him apart from the tribe?
