This week, two unique theater events. Kurt Andersen talks with Alex Timbers, director of a new musical about Imelda Marcos — part history lesson, part disco dance party, but no shoe jokes. A Deaf actor performing in a signed version of a Harold Pinter play explains why on stage, actors’ voices are just a distraction from actual performance. Brazilian cellist Dom La Nena performs live. And Kurt makes small talk at the deathbed of network TV.
