Fascinated by the collision of country and soul music in the Southern states, Hoskyns and photographer Muir MacKean set out on a journey through the American South to explore the phenomenon of primarily black singers and primarily white musicians joining forces in the 1960s to create musical magic in an era of racial tension. From Memphis to Muscle Shoals to Nashville, they sat down with dozens of the architects of what's come to be known as Country Soul to capture a story that is as inspiring as it is historically important.
