The Stanley Brothers were an American bluegrass duo of singer-songwriters and musicians, made up of brothers Carter Stanley (August 27, 1925 – December 1, 1966) and Ralph Stanley (February 25, 1927 – June 23, 2016). Ralph and Carter performed as The Stanley Brothers with their band, The Clinch Mountain Boys, from 1946 to 1966. Ralph kept the band name when he continued as a solo artist after Carter's death, from 1967 until his own death in 2016.
