This year is Memphis' bicentennial, but while there's been Memphis music as long as there's been a Memphis, you can't listen back 200 years. As a result, our three-part Memphis Music Road Map is a de facto centennial (and a little more) of sound. We tell a story of Memphis music's evolution one song at a time, from early blues and the Beale Street sound to the golden age of Sun and Stax and on to the contemporary styles of rock and rap. This first part follows the trail from W.C. Handy to the dawn of World War II.
