Lester Flatt and Earl Scruggs met in 1945 as members of Bill Monroe's band, the Blue Grass Boys. Although only with Monroe for a few years, they helped to define the pattern for all bluegrass bands to follow. In 1948 the two set out on their own, forming their own backing band, the Foggy Mountain Boys. For over 20 years, they were one of the most successful bluegrass bands. Their best known songs include Earl's signature banjo tune, "Foggy Mountain Breakdown", used in the movie "Bonnie and Clyde", and "The Ballad of Jed Clampett" which was the theme song for the "Beverly Hillbillies" TV show.
In 1969 the two went their separate ways. Flatt returned to a more traditional sound with his new band, the Nashville Grass, which included most of the Foggy Mountain Boys. Lester Flatt died in 1979. Scruggs formed the Earl Scruggs Revue with his sons and incorporated rock and modern country influences in his music. He is currently semi-retired but performs occasional concerts.
Flatt and Scruggs were inducted into the Country Music Hall of Fame in 1985 and the International Bluegrass Music Association Hall of Honor in 1991.
