By 1950 Rhythm and Blues was well established as a distinct form of black popular music having shed the generic racial connotations of earlier descriptions. The establishment of new recording studios in Los Angeles New Orleans Cincinnati Houston and Memphis fostered the development of distinctive regional styles with smaller independent labels such as Atlantic King Specialty and Imperial being set up to capitalise on this booming new market. So here we ve got country blues and club blues; drinking songs and risqué songs; vocal groups and instrumental combos. From bebop to boogie gutbucket to gospel honkin and screamin to low down and dirty rock n roll; 112 tracks and not a dud in the bunch!
