From The Washington Post:
Ms. Dickens grew up in dire poverty in West Virginia’s coal country and developed a raw, keening style of singing that was filled with the pain of her hardscrabble youth. She supported herself in day jobs for many years before she was heard on the soundtrack of the 1976 Oscar-winning documentary about coal mining, ”Harlan County, U.S.A.”
Her uncompromising songs about coal mining, such as “Black Lung” and “They Can’t Keep Us Down,” became anthems, and she was among the first to sing of the plight of women trying to get by in the working-class world.
