Mississippi gave the world the blues, then handed the beat to a shy boy from Tupelo who turned it into Rock ’n’ roll. This is a road trip through the places that made the music and the history that shaped them. Stand in the two-room house where Elvis was born and walk the halls of the Mississippi Civil Rights Museum in Jackson. Trade the inland heat for the live oaks and quiet beaches of Ocean Springs, then settle among the columned mansions of Natchez, high on the bluffs above the river. Follow Highway 61 north into the flat, open Delta, where B.B. King’s story is told in Indianola and the GRAMMY Museum brings it right up to date. And in Clarksdale, the music is still played the way it always was: loud, late and a few feet from where you’re standing.
