(Budget priced 4-CD box set) Bluegrass has been called "folk music with overdrive". Here is the story of this vital string-band music that inspired the rockabilly & rock 'n roll boom of the '50s. Bluegrass has never been more popular, in no small way due to the success of the film "O Brother Where Art Thou" and it's accompanying soundtrack. This 99 track compilation features Bill Monroe, Flatt & Scruggs, The Stanley Bros., The Delmore Bros., Grandpa Jones, Gid Tanner & His Skillet Lickers, Ernest V. Stoneman & His Dixie Mountaineers, Uncle Dave Macon, Coon Creek Girls and The Armstrong Twins.
