In this episode, Warren Smith talks about Christmas music with singer-songwriters Andrew Peterson and Keith Getty. Keith Getty and his wife Kristyn have become fixtures in Christian music over the past decade. For the past few years, they've done an annual Christmas tour. This year they're calling it "Irish Christmas: A Celebration of Carols." Stops this year include The Kennedy Center in Washington, DC, and Carnegie Hall in New York.For the past 15 years Andrew Peterson and a circle of musical collaborators have toured the country with a Christmas show called "Behold The Lamb of God." The program tells not just the Christmas story, the coming of the baby Jesus, but rather the full arc of the coming and ultimate second coming of the Messiah. This year, the tour makes stops in Houston, Birmingham, Orlando, Washington, and Nashville, at the historic Ryman Auditorium.
