Joni Mitchell, Carole King, and Carly Simon remain among the most enduring and important women in popular music. Each woman is distinct: King is the product of outer-borough, middle-class New York City; Mitchell is a granddaughter of Canadian farmers; and Simon is a child of the Manhattan intellectual upper crust. They collectively represent, in their lives and their songs, a great swath of American girls who came of age in the late 1960s.
