Wanda LaVonne Jackson (born October 20, 1937)is an American retired singer and songwriter. Since the 1950s, she has recorded and released music in the genres of rock, country and gospel. She was among the first women to have a career in rock and roll, recording a series of 1950s singles that helped give her the nickname "The Queen of Rockabilly". She is also counted among the first female stars in the genre of country music.

Janis Darlene Martin (March 27.1940 September 3, 2007) was an American rockabilly and country music singer. She was one of the few women working in the male-dominated rock and roll music field during the 1950s and one of country music's early female innovators. Martin was nicknamed the Female Elvis for her dance moves on stage, similar to those of Elvis Presley.

Barbara Pittman (April 6, 1938 October 29, 2005). Her claim to fame is that she was the only female artist signed to Sam Phillips' Sun Records other women recorded for the label, but only Pittman was one of the few female singers to record at Sun Studio given a contract. That alone would secure her place as a footnote in music history, but Pittman also cut one exalted rockabilly classic during her Sun years: "I Need a Man."
