Answer by taking a quote from the following article:

Polly Jean Harvey was born on 9 October 1969 in Bridport, Dorset, the second child of Ray and Eva Harvey, who owned a stone quarrying business, and grew up on the family's farm in Corscombe. During her childhood, she attended school in nearby Beaminster, where she received guitar lessons from folk singer-songwriter Steve Knightley, and her parents introduced her to music that would later influence her work, including blues music, Captain Beefheart and Bob Dylan. Her parents were avid music fans and regularly arranged get-togethers and small gigs; among their oldest friends was Ian Stewart. As a teenager, Harvey began learning saxophone and joined an eight-piece instrumental group Bologne, based in Dorset.

As Harvey embarked on her solo career, she explored collaborations with other musicians. In 1995 she released her third studio album, To Bring You My Love, featuring former bandmate John Parish, Bad Seeds multi-instrumentalist Mick Harvey and French drummer Jean-Marc Butty, all of whom would continue to perform and record with Harvey throughout her career. The album was also her first material to be produced by Flood. Simultaneously a more blues-influenced and more futuristic record than its predecessors, To Bring You My Love showcased Harvey broadening her musical style to include strings, organs and synthesisers. Rolling Stone said in its review that "Harvey sings the blues like Nick Cave sings gospel: with more distortion, sex and murder than you remember. To Bring You My Love was a towering goth version of grunge." During the successive tours for the album, Harvey also experimented with her image and stage persona.  The record generated a surprise modern rock radio hit in the United States with its lead single, "Down by the Water." Three consecutive singles -- "C'mon Billy", "Send His Love to Me" and "Long Snake Moan" -- were also moderately successful. The album was a commercial success selling one million copies worldwide including 370,000 in the United States. It was also certified Silver in the United Kingdom within seven months of its release, having sold over 60,000 copies. In the United States, the album was voted Album of the Year by The Village Voice, Rolling Stone, USA Today, People, The New York Times and the Los Angeles Times. Rolling Stone also named Harvey 1995's Artist of the Year and Spin ranked the album third in The 90 Greatest Albums of the '90s, behind Nirvana's Nevermind (1991) and Public Enemy's Fear of a Black Planet (1990).  In 1996, following the international success of To Bring You My Love and other collaborations, Harvey began composing material that would end up on her fourth studio album, during what she referred to as "an incredibly low patch." The material diverged significantly from her former work and introduced electronica elements into her song-writing. During recording sessions in 1997 original PJ Harvey Trio drummer Rob Ellis rejoined Harvey's band, and Flood was hired again as producer. The sessions, which continued into April the following year, resulted in Is This Desire? (1998). Though originally released to mixed reviews in September 1998, the album was a success and received a Grammy Award nomination for Best Alternative Music Performance. The album's lead single, "A Perfect Day Elise," was moderately successful in the United Kingdom, peaking at number 25 on the UK Singles Chart, her most successful single to date.
