There's a new movie opening this weekend. It's called "A Late Quartet," the story of a string quartet that's been together for 25 years. The movie does a good job portraying the very close, and sometimes very messy, relationships that develop when a quartet plays together for 25 years. Jealousy, passion, conflict, boredom. In the final scene, we see them on stage playing Beethoven's Op. 131 quartet. You can hear some of the beautiful intimacy and beautiful messiness of the human condition in Beethoven's music. The film's stars, including Christopher Walken and Philip Seymour Hoffman, do a passable job of pretending to play instruments. Today, we'll hear the real musicians who recorded soundtrack of "A Late Quartet," the Brentano Quartet.
