Charlie Louvin was one half of the country-gospel duo the Louvin Brothers. The group popularized the concept of close-harmony signing, and introduced the art form to the Everly Brothers and many other hugely successful rock and roll acts. The Louvin Brothers toured with Elvis Presley in the 1950s, and scored hits with "I Don't Believe You've Met Me Baby" and "When I Stop Dreaming." Louvin went solo in the 1960s and began putting his own hits on the charts. There was a tremendous revival of interest in Louvin's career over the past decade as groups like the Raconteurs acknowledged his influence. He played at Bonnaroo in 2007.
