Country music is generally reckoned to have resulted from the interaction of British and Irish folk music, as brought by Tennessee’s first Anglo settlers, with other ethnic music, including the spirituals and gospel hymns sung by African American slaves and their descendants. It first acquired its current form during the 1920s. As radios and record players became widely available, the recording industry took off and Nashville became the base for musicians of the mid-South. Local radio station WSM – “We Shield Millions”, the slogan of its insurance-company sponsor – first broadcast on October 5, 1925, swiftly established itself as a champion of the country sound. Two years later, at the start of his Barn Dance show, compere George D. Hay announced “for the past hour we have been listening to music taken largely from Grand Opera, but from now on we will present The Grand Ole Opry”. This piece of slang became the name of America’s longest-running radio show, still broadcast live out to millions two to three nights per week on WSM-AM (650). Soon outgrowing the WSM studios, the show moved in 1943 to a former tabernacle – the Ryman Auditorium. There it acquired a make-or-break reputation; up-and-coming singers could only claim to have made it if they had gone down well at the Opry. Among thousands of hopefuls who tried to get on the show was Elvis Presley, advised by an Opry official in 1954 to stick to truck-driving.
The decade of prosperity after World War II witnessed country’s first commercial boom. Recording studios, publishing companies and artists’ agencies proliferated in Nashville and the major labels recognized that a large slice of the (white) record-buying public wanted something less edgy than rockabilly. The easy-listening Nashville Sound they came up with, pioneered by Patsy Cline and Jim Reeves, is kept alive today by million-selling artists like Taylor Swift, Carrie Underwood and Lady Antebellum.
