Jimmie Rodgers and the Carter Family are widely considered to be important early country musicians. From Scott County, Virginia, the Carters had learned sight reading of hymnals and sheet music using solfege.[citation needed] Their songs were first captured at a historic recording session in Bristol, Tennessee, on August 1, 1927, where Ralph Peer was the talent scout and sound recordist.[13][14] A scene in the movie O Brother, Where Art Thou? depicts a similar occurrence in the same timeframe.
