Which of the named artists was nicknamed “Madonna” before Madonna Louise Ciccone arrived on the music scene?

Joan Chandos Baez (born January 9, 1941) is an American singer, songwriter, musician and activist, one of three daughters to a Mexican father and a Scottish mother.

In 1958, her father, a prominent physicist, accepted a faculty position at Massachusetts Institute of Technology, and the family moved from the San Francisco area to Boston. At that time, Boston was a centre of the increasingly popular folk-music scene in which the 18 year old Joan Baez played a progressively active part. Her recognised talent led to her appearance at the 1959 Newport Folk Festival where she enhanced her reputation as a folk and gospel singer and effectively launched her professional career.

With her pure, three-octave soprano voice, her long hair, looks, and presence, she earned the nickname "Madonna" because she represented the "Earth Mother" for the 1960s generation.

In the 60 or so years since the Newport Folk Festival, Baez has produced over 30 albums and has displayed a continuing commitment to political and social activism in the fields of nonviolence, civil rights, human rights and the environment. Baez was inducted into the Rock and Roll Hall of Fame on April 7, 2017.
