About Maybelle Carter
"Mother" Maybelle Carter was an American country musician and "among the first" to use the Carter scratch, with which she "helped to turn the guitar into a lead instrument." It was named after her. She was a member of the original Carter Family act from the late 1920s until the early 1940s and a member of the Carter Sisters and Mother Maybelle group. The Carter Family was one of the first commercial rural country music groups. Her final such work, a two-record set released on Columbia Records, placed on Billboard's best-selling country albums chart in 1973 when she was 64. Carter made occasional solo recordings during the 1960s and 1970s, usually full-length albums.
