About the event. Named one of the 10 best albums of the decade, Behold the Lamb of God is a collection of songs about Jesus. Since 2000, Andrew Peterson and his friends have performed Behold the Lamb around the country, telling again and again this true myth, as C.S. Lewis called it, this tale that's bigger than life, but is—astonishingly—true. The tour has become a yearly tradition not just for Andrew and the other artists on the tour, but for families and churches who attend the live concert each season.
