The Tony Awards are this weekend, and the heaviest contender is the filthiest show on Broadway, The Book of Mormon. Robert Lopez, the composer and co-creator, sits down at the piano to show Kurt Andersen the recipe for his cocktail of sweet and snarky. We also go Off-Broadway to the most innovative, extraordinary show in New York, Sleep No More — an installation performance piece that riffs on Macbeth. Plus The Antlers perform songs from their new album live in the studio.
