Bristol sessions

The Bristol Sessions are considered the "Big Bang" of modern country music. They were held in 1927 in Bristol, Tennessee by Victor Talking Machine Company producer Ralph Peer. Bristol was one of the stops on a two-month, $60,000 trip that took Peer through several major southern cities and yielded important recordings of blues, ragtime, gospel, ballads, topical songs, and string bands. The Bristol Sessions marked the commercial debuts of Jimmie Rodgers and the Carter Family. As a result of the influence of these recording sessions, Bristol has been called the "birthplace of country music". Since 2014, the town has been home to the Birthplace of Country Music Museum.

Commercial recordings of country music had begun in 1922. Among these very early artists were Vernon Dalhart, who recorded the million-selling Wreck of the Old 97, Ernest Stoneman from Galax, Virginia, Henry Whitter, A.C. (Eck) Robertson, who recorded the first documented country record along with Henry C. Gilliland ("Sallie Gooden" b/w "Arkansaw Traveler"), and Uncle Dave Macon. However, any "hillbilly" artists who recorded had to travel to the New York City studios of the major labels, and many artists, including Dalhart, were not true "hillbilly" artists but instead crossed over from other genres. ("Hillbilly" is used here to distinguish the largely secular folk music of the region from gospel and blues, and is not meant as a pejorative.)

Okeh Records and later Columbia Records had sent producers around the South in an attempt to discover new talent. Peer, who worked for Okeh at the time, recorded Fiddlin' John Carson using the old acoustic method (known for its large intrusive sound-gathering horn) in 1924, at the behest of the Okeh dealer in Atlanta, Georgia, Polk Brockman. Despite Peer's belief that the record was of poor quality, the 500 copies made of "Cluck Old Hen" sold out in weeks. This experience convinced Peer of the potential for "hillbilly" music.
