Roberta chats with Paul Chan about his installation, “Pillowsophia,” at PAFA’s Morris Gallery. The haunting piece is a hollow hooded figure made of black nylon placed high against a wall. In continuous motion from wind blown into its cavity by a powerful and noisy industrial fan, the piece is engineered and stitched in such a way that it dances what seems like an ecstatic death dance. A response to the times, which are filled with violence against black men, the piece is powerful and emotionally moving.
