Doo wop performers were originally almost all black, but a few white and integrated groups soon became popular. These included a number of Italian-American groups such as Dion & the Belmonts, while others added female vocalists and even formed all-female groups in the nearly universally male field; these included The Queens and The Chantels. The 1950s saw a number of brief fads that went on to have a great impact on future styles of music. Performers like Pete Seeger and The Weavers popularized a form of old-time revival of Anglo-American music. This field eventually became associated with the political left-wing and Communism, leading to a decline in acceptability as artists were increasingly blacklisted and criticized. Nevertheless, this form of pop-folk exerted a profound influence in the form of 1950s folk-rock and related styles. Alongside the rather sporadic success of popularized Anglo folk music came a series of Latin dance fads, including mambo, rumba, chachachá and boogaloo. Though their success was again sporadic and brief, Latin music continued to exert a continuous influence on rock, soul and other styles, as well as eventually evolving into salsa music in the 1970s. Beginning in the late 1920s, a distinctive style first called "old-timey" or "hillbilly" music began to be broadcast and recorded in the rural South and Midwest; early artists included the Carter Family, Charlie Poole and his North Carolina Ramblers, and Jimmie Rodgers. The performance and dissemination of this music was regional at first, but the population shifts caused by World War II spread it more widely. After the war, there was increased interest in specialty styles, including what had been known as "race" and "hillbilly" music; these styles were renamed to "rhythm and blues" and "country and western", respectively. Major labels had some success promoting two kinds of country acts: Southern novelty performers like Tex Williams and singers like Frankie Laine, who mixed pop and country in a conventionally sentimental style. This period also saw the rise of Hank Williams, a white country singer who had learned the blues from a black street musician named Tee-Tot, in northwest Alabama. Before his death in 1953, Hank Williams recorded eleven singles that sold at least a million copies each and pioneered the Nashville sound. The Nashville sound was a popular kind of country music that arose in the 1950s, a fusion of popular big band jazz and swing with the lyricism of honky-tonk country.
