Tori Sampson’s This Land Was Made is a steamy gumbo of history, humor, and imagination. Directed by Taylor Reynolds, it serves up a fictive account of the origins of the Black Panther Party for Self-Defense, founded by Huey P. Newton and Bobby Seale in Oakland, Calif., in 1966. Although the play has some structural flaws, it invites one to ponder the issues that animated this revolutionary social organization—racist police brutality and economic injustice—and to consider how they still resonate today.
