The Stanley Brothers were a legendary American bluegrass duo made up of brothers Carter and Ralph Stanley. The Stanley's style can best be described as a traditional "mountain soul" sound that remained close to the Primitive Baptist vocal stylings they learned from their parents and others near their southwestern Virginia home. Ralph has often used the expression "...old-time, mountain style, what they call 'bluegrass' music", to differentiate the Stanley's sound from mainstream bluegrass. Ralph is still performing as of 2010. Among the musicians who have played in the revived Clinch Mountain Boys are Ricky Skaggs, Keith Whitley, Larry Sparks, Curly Ray Cline, Jack Cooke, Roy Lee Centers, Charlie Sizemore, Ray Goins, and Ralph Stanley II. Ralph's career received a big boost with his prominent role on the phenomenally successful soundtrack recording of the 2000 film, O Brother, Where Art Thou?
