Music, it seems, needs a picture to settle in our minds. The better the picture, the better is the reception. There are quite a few pictures that made the way for Flatt& Scruggs. The powerful 1960ies Bonnie and Clyde movie was literally written around their 1948 recording of the "Foggy Mountain Breakdown" and their biggest commercial success was the theme to "The Beverly Hillbillies" TV series.
They embarked their careers after quitting Bill Monroe's Blue Grass Boys in 1948. Before that young Earl Scruggs revolutionised the sound of Bluegrass with his forceful, rolling three finger style. Along with Lester Flatt he developed a distinct traditional form of Bluegrass, whereas Monroe was more bluesier. But Monroe, jealous and watchful over what music he once created, was not happy with so much competition keeping them out of the Opry for quite some time.
Flatt& Scruggs recorded for 21 years, before they split in a dispute of adopting singer songwriters material. Flatt stayed to his traditional style until his death in 1979. Scruggs is still playing around often, collaborating with the big stars of today's pop music.
