Osborne Brothers were one of the most popular and innovative bluegrass groups of the post-war era, taking the music into new directions and gaining a large audience. Among their most notable achievements are their pioneering, inventive use of amplification, twin harmony banjos, steel guitars, and drums. They were the first bluegrass group to expand the genre's sonic palette in such a fashion.

Bobby and Sonny Osborne were born in Hyden, Ky., but raised in Dayton, Ohio. As children, their father instilled a love for traditional music. Bobby picked up the electric guitar as a teenager, playing in various local bands. A few years after his brother began playing the guitar, Sonny picked up the banjo. In 1949, Bobby formed a duo with banjoist Larry Richardson. The pair was hired by a West Virginian radio station and stayed in the state for a while, eventually hooking up with the Lonesome Pine Fiddlers.

The Osbornes played the Grand Ole Opry and bluegrass festivals across America. Later in the '70s, the duo returned to a more traditional sound. Throughout the '80s and '90s they stuck to this sound, playing concerts and festivals frequently. ~ Stephen Thomas Erlewine, All Music Guide
