On the heels of his latest controversial release "Stockholm Syndrome," the always-provocative Nashville songsmith Derek Webb hits the road again with his wife Sandra McCracken. Each have recorded new collections of sacred music - Derek's worship-oriented "Feedback" (to be released), and Sandra's record of hymns called "In Feast or Fallow." The tour is titled after GK Chesterton's assertion that "mathematicians try to build a bridge across the infinite and poets simply swim in the sea."
