(2-CD Set) Father of bluegrass music Bill Monroe summarized the nature of the music, basically comprising hillbilly string band styles with harmony vocals also influenced by blues and folk traditions. It has enjoyed periodic popular revivals, through 60s/70s devotees like the Flying Burrito Brothers and Clarence White and the use of Eric Weissberg's "Duelling Banjos" in the 1973 John Boorman movie "Deliverance". In the 21st Century, the Coen Brothers' good-natured comedy "O Brother Where Art Thou?" promoted bluegrass with its soundtrack. This collection features The Stanley Brothers, Bill Monroe, The Delmore Brothers, Flatt & Scruggs & Charlie Monroe.
