Kimberley Ann "Kim" Deal (born June 10, 1961) is an American singer, songwriter and musician, best known as the former bassist and backing vocalist of the alternative rock band Pixies, and the lead vocalist and rhythm guitarist for The Breeders. Deal joined Pixies in January 1986 as the band's bassist, adopting the stage name Mrs. John Murphy for the albums Come on Pilgrim and Surfer Rosa. Following Doolittle and The Pixies' hiatus, she formed The Breeders with Tanya Donelly, Josephine Wiggs and later introduced her identical twin sister Kelley Deal. The Pixies broke up in early 1993, and Deal returned her focus to The Breeders, who released the platinum-selling album Last Splash in 1993.

Deal became the bassist and backing vocalist for Pixies in January 1986, after answering an advertisement in the Boston Phoenix that said, ""Band seeks bassist into Husker Du and Peter, Paul and Mary. Please - no chops." Deal was the only person to call them, even though her main instrument was guitar. She borrowed her sister Kelley's bass guitar to use in the band. To complete the lineup, she suggested they hire David Lovering as drummer, a friend of her husband, whom she met at her wedding reception. For the release of the band's first recording Come on Pilgrim (1987), Deal used the nom de disque "Mrs. John Murphy" in the liner notes. She chose the name as an ironic feminist joke, after conversing with a lady who wished to be called only by her husband's name as a form of respect.  For Surfer Rosa (1988), Deal sang lead vocals on the album's only single, "Gigantic" ( sample ), which she co-wrote with Black Francis. Doolittle followed a year later, with Deal contributing the song "Silver" and appearing on slide guitar. By this time, however, tensions began to develop between her and Francis, with bickering and standoffs between the two marring the album's recording sessions. This led to increased stress between the band members. Murphy commented that during the sessions, it "went from just all fun to work". Exhaustion, from releasing three records in two years and constant touring, contributed to the friction, particularly between Francis and Deal.  The tension and exhaustion culminated at the end of the US "Fuck or Fight" tour, where they were too tired to attend the end-of-tour party. The band soon announced a hiatus.Answer this question using a quote from the following article:
