Dock Boggs was born Moran Lee "Dock" Boggs in 1898 and died on his birthday in 1971. Two of Dock's classic songs were on Harry Smith's 1951 Anthology of American Folk Music. A coal miner most of his life, Dock Boggs began recording in the 20s and like many treasures hidden away in the hills, he stayed hidden while working his trade and living with his back and hands. He was one more discovery in the 1960s from the youthful pursuit of musicians like Mike Seeger, who sought out their folk heroes to perform again live and likewise head into the studios to record. A round of applause for this good sense. Virginia born, the youngest of ten children, Dock Boggs drew much of his music from the landscape and those found therein: African-American itinerant players, camps, stories heard around the table, in the field. All his recordings are gems, perhaps the easiest to be found are on the Folkways and Smithsonian labels.
An excellent piece on the coal miner and "up-picking" banjo player by Jack Wright may be found on the link below.
