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 of sound. This second part follows a trail from B.B. King's first recordings to the rise of rock 'n' roll and soul, on to Al Green's rejection of secular soul, the emergence of alternative Memphis and Beale Street's decline.
