Some context: Gong are an international progressive rock band that incorporates elements of jazz and space rock into their musical style. The group was formed in Paris in 1967 by Australian musician Daevid Allen and English vocalist Gilli Smyth. Band members have included Didier Malherbe, Pip Pyle, Steve Hillage, Mike Howlett, Pierre Moerlen, Bill Laswell and Theo Travis. Others who have played on stage with Gong include Don Cherry, Chris Cutler, Bill Bruford, Brian Davison, Dave Stewart and Tatsuya Yoshida.
1972 saw the start of increasing line-up disruption for Gong. Laurie Allan left in April to be replaced by Mac Poole, then Charles Hayward and then Rob Tait, before returning again late in the year. Gilli Smyth left for a time, returning to Deia to look after she and Daevid Allen's baby son, and was replaced by Diane Stewart, who was the partner of Tait and the ex-wife of Graham Bond. Christian Tritsch moved to guitar and was replaced on bass by former Magma member Francis Moze, while the band's sound was expanded with the addition of synthesizer player Tim Blake.  In October they were one of the first acts to sign to Richard Branson's fledgling Virgin Records label, and in late December traveled to Virgin's Manor Studio in Oxfordshire, England, to record their third album, Flying Teapot. As they settled in, they were played a rough mix of Mike Oldfield's Tubular Bells, then already in production. Towards the end of their recording sessions they were joined by English guitarist Steve Hillage, whom they had met a few weeks earlier in France playing with Kevin Ayers, and who had replaced Oldfield in Ayers' band. He arrived too late to contribute much to the album, but would soon become a key component in the Gong sound.  Flying Teapot was released on 23 May 1973, the same day as Tubular Bells, and was the first installment of the Radio Gnome Invisible trilogy, which expounded upon the (previously only hinted at) Gong mythology developed by Allen. The second part, Angel's Egg, followed in December, now featuring the 'classic' rhythm section of Mike Howlett on bass and Pierre Moerlen on drums. In early 1974 Moerlen left to work with the French contemporary ensemble Les Percussions de Strasbourg and Smyth left to give birth to she and Allen's second son. They were replaced once again by Rob Tait and Diane Stewart, and the band moved from its French base at Pavillon du Hay to an English one at Middlefield Farm, near Witney, Oxfordshire. Moerlen, and later Smyth, returned in order to complete the trilogy with the album You, but by the time of its release, in October 1974, Moerlen was back with Les Percussions de Strasbourg and Smyth had settled permanently in Deia with her young sons. Prior to touring in support of You, Allen visited Smyth and the boys in Deia, while the rest of the band, including the departed Moerlen, recorded the basic tracks for Hillage's first solo album, Fish Rising. Moerlen was initially replaced in Gong by a succession of stand-ins (Chris Cutler, Laurie Allan and Bill Bruford) until former Nice and Refugee drummer Brian Davison took the job in early 1975. Smyth had already been replaced by Hillage's partner Miquette Giraudy.  In June 1974, Camembert Electrique was given a belated UK release by Virgin, priced at 59p, the price of a typical single at the time; a promotional gimmick which they had used before for Faust and would use again for a reggae compilation in 1976. These ultra-budget albums sold in large quantities because of the low price, but the pricing made them ineligible for placement on the album charts. The hope was that new fans would be encouraged to buy the groups' other albums at full price.

Some context: 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.
