Otis Redding. Booker T and the M.G.s. Eddie Floyd. Isaac Hayes. The Staples Sisters. What do all of these classic soul and R&B artists have in common? Stax Records. As he toured the history of the Civil Rights Movement this summer, host John Fea included a stop at the Stax Museum (@StaxMemphis) in Memphis, Tennessee. Eager to relive the experience and share such attractions as a floor-to-ceiling record room and Isaac Hayes’s gold-plated Cadillac, Fea and producer Drew Dyrli Hermeling are joined by the museum’s executive director, Jeff Kollath. They discuss the importance of that “Memphis Sound” for the city as well as creating a “usable past” with popular music history.
