Kim Deal (born June 10, 1961) is an American musician.
She was born and raised in Dayton, Ohio, with her twin sister Kelley. In high school she was a cheerleader and often got into conflicts with authority. Deal married and moved to Boston with her husband, John Murphy. She became a bassist and vocalist for the seminal alternative rock band The Pixies in 1986, after answering an advert for a female bassist into Hüsker Dü and Peter, Paul and Mary. Initially she went under the stage name "Mrs. John Murphy." In 1989, in order to play a larger vocal role in a band, she teamed up with Tanya Donelly and Josephine Wiggs to form a band called The Breeders, who released their debut album, Pod, in 1990.
