Stage review: Moving, funny 'Sisters Grey' holds much promise

Pittsburgh Post-Gazette: If we're honest, we realize that race, ethnicity and even color are social constructs based on conventional, often unexamined, traditions, assumptions, affiliations and so on. "The Sisters Grey," an intriguing new comedy getting a shakedown cruise (read workshop) at the August Wilson Center, focuses on several such social constructs: "black," "Jewish" and the one that ensnares us all, "family." The first suggests both more and less than skin color. The second can be a religion, an ethnicity and a definition, often self-imposed. And the third is a bond variously defined, recognized, honored or denied.
