Black Power! Yes, indeed. This man espoused beliefs that many would consider black nationalist. I've only read Fences. I was surprised to read that Mr. Wilson didn't consider Fences his signature play (251). Nor was it his favorite. ( It was his least favorite.) These interviews involved little comment on his marriages or his daughter. I did learn that he had lived in Pittsburgh, Pennsylvania; St. Paul, Minnesota; and Seattle, Washington, in that order.
This would satisfy a devoted fan of Mr.Wilson.
