The roots of commercial country music are generally traced to 1927, when music talent scout Ralph Peer recorded Jimmie Rodgers and The Carter Family. Popular success was very limited, though a small demand spurred some commercial recording. After World War II, there was increased interest in specialty styles like country music, producing a few major pop stars. The most influential country musician of the era was Hank Williams, a bluesy country singer from Alabama. He remains renowned as one of country music's greatest songwriters and performers, viewed as a "folk poet" with a "honky-tonk swagger" and "working-class sympathies". Throughout the decade the roughness of honky-tonk gradually eroded as the Nashville sound grew more pop-oriented. Producers like Chet Atkins created the Nashville sound by stripping the hillbilly elements of the instrumentation and using smooth instrumentation and advanced production techniques. Eventually, most records from Nashville were in this style, which began to incorporate strings and vocal choirs.
