The Delivery Man was originally intended as a concept album about a delivery man in the Deep South. Elvis Costello kept the spirit, if not the story. Recorded in Mississippi, these songs are soaked in the region’s sounds: The Imposters ignite the simmering soul-rocker “Bedlam”, Emmylou Harris’ pure harmonies illuminate country ballad “Heart Shaped Bruise” and Lucinda Williams’ smoky snarl cuts through the rollicking “There’s a Story in Your Voice”.
