Kim Deal (born Kimberley Ann Deal on June 10, 1961) is an American musician.
She was born and raised in Dayton, Ohio, with her twin sister Kelley Deal. 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 Husker Du and Peter, Paul & 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.
Deal recorded and performed with The Pixies until 1992, when the group split, largely because of increasing tension between her and frontman Black Francis. A year later, the Breeders released their second album, Last Splash, to critical acclaim and considerable commercial success.
At the height of The Breeders' popularity in the mid-1990s, they scored a number of MTV hits, including "Cannonball" and "Divine Hammer." Although the band went into stasis in 1994, they never officially split up, and in 2002 returned with a new album, Title TK. During this 8 year hiatus, Kim Deal kept busy by forming, recording, and touring with The Amps. She also produced albums for other groups, most notably fellow Dayton band Guided by Voices.
