Kimberley Ann Deal (born June 10, 1961) is an American musician. She was the original bassist and co-vocalist in the alternative rock band Pixies from 1986 to 1993 and 2004 to 2013, and is the frontwoman of the Breeders, which she formed in 1989. Deal joined Pixies in January 1986, 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 of Throwing Muses, Josephine Wiggs of the Perfect Disaster, and Britt Walford of Slint; following the band's debut album Pod, her twin sister Kelley Deal replaced Donelly. Pixies broke up in early 1993, and Deal returned her focus to the Breeders, who released the platinum-selling album Last Splash in 1993, featuring the popular single "Cannonball". In 1994, the Breeders went on hiatus after Kelley entered drug rehabilitation. During the band's hiatus, Deal adopted the stage name Tammy Ampersand and formed the short-lived rock band the Amps, recording a single album, Pacer, in 1995. After her own stint in drug rehabilitation, Deal eventually reformed the Breeders with a new line-up for two more albums, Title TK in 2002 and Mountain Battles in 2008. During that time, she also returned to Pixies when the band reunited in 2004. In 2013, Deal left Pixies to concentrate on the Breeders, after that band's most famous line-up reunited for a new series of tours celebrating the 20th anniversary of Last Splash. In 2018, the Breeders released their fifth album All Nerve, the first album to reunite the Deals, Wiggs, and Macpherson since Last Splash.
