In the mid 1950's R&B started to move away from it's electrified country-blues phase and into a more commercial, sophisticated form. R&B in the late 50's then saw an increase in the influence of gospel music as performers from that genre started moving into secular music. These developments would lead to the creation of the two largest labels for the next step in the evolution of R&B. The form would be called Soul music by the 60's and the labels Stax\Volt out of Memphis, TN and Motown out of Detriot , MI would be the commercial and creative powerhouses (although Motown would dwarf Stax commercially). The following playlist focuses on the raw, often hard rocking, funky Southern Soul that came out of Stax and it's sometime distributor and collaborator Atlantic Records.
