It's a big week for Bob Boilen! He celebrated his birthday earlier in the week and his first book, Your Song Changed My Life, comes out today. He celebrated on the show today with some wonderful pop music by the band Free Cake For Every Creature and a beautiful Grateful Dead cover courtesy of the National. While Bob leaves the studio to celebrate, Robin plays a joyous cut from the Nobility and an atmospheric track from the supergroup Minor Victories.
