Question: When were the performers of Master Mixes established?

full_context: Document 1: The Remixes (Dannii Minogue album): The Remixes is a double-disc remixes compilation album by Australian pop–dance singer Dannii Minogue. It was released by Mushroom Records on 3 November 1998 in Australia. Since the compilation was a budget release, it was ineligible to chart on the Australian albums chart.
Document 2: Post-punk: The original post-punk movement ended as the bands associated with the movement turned away from its aesthetics, often in favor of more commercial sounds. Many of these groups would continue recording as part of the new pop movement, with entryism becoming a popular concept. In the United States, driven by MTV and modern rock radio stations, a number of post-punk acts had an influence on or became part of the Second British Invasion of "New Music" there. Some shifted to a more commercial new wave sound (such as Gang of Four), while others were fixtures on American college radio and became early examples of alternative rock. Perhaps the most successful band to emerge from post-punk was U2, who combined elements of religious imagery together with political commentary into their often anthemic music.
Document 3: Hard rock: Established bands made something of a comeback in the mid-1980s. After an 8-year separation, Deep Purple returned with the classic Machine Head line-up to produce Perfect Strangers (1984), which reached number five in the UK, hit the top five in five other countries, and was a platinum-seller in the US. After somewhat slower sales of its fourth album, Fair Warning, Van Halen rebounded with the Top 3 album Diver Down in 1982, then reached their commercial pinnacle with 1984. It reached number two on the Billboard album chart and provided the track "Jump", which reached number one on the singles chart and remained there for several weeks. Heart, after floundering during the first half of the decade, made a comeback with their eponymous ninth studio album which hit number one and contained four Top 10 singles including their first number one hit. The new medium of video channels was used with considerable success by bands formed in previous decades. Among the first were ZZ Top, who mixed hard blues rock with new wave music to produce a series of highly successful singles, beginning with "Gimme All Your Lovin'" (1983), which helped their albums Eliminator (1983) and Afterburner (1985) achieve diamond and multi-platinum status respectively. Others found renewed success in the singles charts with power ballads, including REO Speedwagon with "Keep on Loving You" (1980) and "Can't Fight This Feeling" (1984), Journey with "Don't Stop Believin'" (1981) and "Open Arms" (1982), Foreigner's "I Want to Know What Love Is", Scorpions' "Still Loving You" (both from 1984), Heart’s "What About Love" (1985) and "These Dreams" (1986), and Boston's "Amanda" (1986).
Document 4: Post-punk: Artists such as Gary Numan, the Human League, Soft Cell, John Foxx and Visage helped pioneer a new synthpop style that drew more heavily from electronic and synthesizer music and benefited from the rise of MTV. Post-punk artists such as Scritti Politti's Green Gartside and Josef K's Paul Haig, previously engaged in avant-garde practices, turned away from these approaches and pursued mainstream styles and commercial success. These new developments, in which post-punk artists attempted to bring subversive ideas into the pop mainstream, began to be categorized under the marketing term new pop.
Document 5: Duran Duran: Duran Duran () are an English new wave band formed in Birmingham in 1978. The band were one of the most successful acts of the 1980s, but by the end of the decade, membership and music style changes challenged the band before a resurgence in the early 1990s. The group were a leading band in the MTV-driven Second British Invasion of the US in the 1980s. They achieved 14 singles in the top 10 of the UK Singles Chart and 21 in the US "Billboard" Hot 100, and have sold over 100 million records worldwide.
Document 6: Master Mixes: Master Mixes is a remix EP by Duran Duran. This double 12" compilation was released commercially in the United States by Capitol under the production label of Masterdisk Corporation and in Brazil by EMI in 1987.
Document 7: Carnival (EP): Carnival is a dance music EP by Duran Duran, originally released in various markets around the world in September 1982 by EMI.
Document 8: Second British Invasion: During the Second British Invasion, established British acts such as Queen, David Bowie, Paul McCartney, Phil Collins, Rod Stewart and Elton John saw their popularity increase; a few acts that dated to the era of the original British Invasion, including George Harrison, Eddy Grant, The Hollies and The Moody Blues, had their last major hits in this time frame. Counting his work with Genesis, Collins had more top 40 hits on the Billboard Hot 100 chart during the 1980s than any other artist.
Document 9: Only After Dark (album): "Only After Dark" is a compilation album that was compiled by Nick Rhodes and John Taylor from Duran Duran, and recreates a night at Birmingham's Rum Runner nightclub, during the post punk days of the late 70s/early 80s when a new sound of glam/punk/electronica started to crystallize. The CD captures some of the discs that Nick spun when he was deejaying for £10 a night at the club and Duran Duran were the resident band. The inspiration for it came when in 2000 John and Nick spent hours selecting 50 tracks for a 4-hour radio broadcast entitled "A Night At The Rum Runner". The 18 track CD was released on 8 May 2006 and presented in a silver gatefold card sleeve in shocking pink metallic print featuring photographs taken from this period, first published in the book "Duran Duran Unseen" by Paul Edmond, the front cover photo being of fashion designer Patti Bell.
Document 10: Hard rock: Bon Jovi's third album, Slippery When Wet (1986), mixed hard rock with a pop sensitivity and spent a total of 8 weeks at the top of the Billboard 200 album chart, selling 12 million copies in the US while becoming the first hard rock album to spawn three top 10 singles — two of which reached number one. The album has been credited with widening the audiences for the genre, particularly by appealing to women as well as the traditional male dominated audience, and opening the door to MTV and commercial success for other bands at the end of the decade. The anthemic The Final Countdown (1986) by Swedish group Europe was an international hit, reaching number eight on the US charts while hitting the top 10 in nine other countries. This era also saw more glam-infused American hard rock bands come to the forefront, with both Poison and Cinderella releasing their multi-platinum début albums in 1986. Van Halen released 5150 (1986), their first album with Sammy Hagar on lead vocals, which was number one in the US for three weeks and sold over 6 million copies. By the second half of the decade, hard rock had become the most reliable form of commercial popular music in the United States.
Document 11: Get Ready for This: In 2013, American DJ/producer Steve Aoki released a remix of "Get Ready for This" on Byte Records as part of a forthcoming 2 Unlimited greatest hits album. The Rap and Orchestral mixes featured on the original "Get Ready for This" single were also included.
Document 12: List of UK Singles Chart number ones of the 1980s: American entertainer Madonna was the most successful act of the decade in terms of number - one singles. She had six number ones: ``Into the Groove ''(1985);`` Papa Do n't Preach'', ``True Blue ''(both 1986);`` La Isla Bonita'', ``Who's That Girl ''(both 1987); and`` Like a Prayer'' (1989). George Michael had significant involvement with seven number - one singles; he was also involved with Band Aid single ``Do They Know It's Christmas? ''but his contribution was less significant. He had two number - one singles as a solo artist, four as a member of pop duo Wham!, and one as a duet with Aretha Franklin. The following artists achieved three or more number - one hits during the 1980s.
Document 13: The K&D Sessions: The K&D Sessions is the second DJ mix compilation album by the Vienna-based duo Kruder & Dorfmeister. Released by Studio !K7 in 1998 to glowing reviews, the album features two original songs with the remixes.
Document 14: Seven and the Ragged Tiger: Seven and the Ragged Tiger is the third studio album by English new wave band Duran Duran. It was released on 21 November 1983 by EMI. It was the band's first and only number one album on the UK Albums Chart, and would prove to be the last studio album for the band's most famous line-up until 2004's "Astronaut".
Document 15: Phonograph record: Also in the late 1970s, "direct-to-disc" records were produced, aimed at an audiophile niche market. These completely bypassed the use of magnetic tape in favor of a "purist" transcription directly to the master lacquer disc. Also during this period, half-speed mastered and "original master" records were released, using expensive state-of-the-art technology. A further late 1970s development was the Disco Eye-Cued system used mainly on Motown 12-inch singles released between 1978 and 1980. The introduction, drum-breaks, or choruses of a track were indicated by widely separated grooves, giving a visual cue to DJs mixing the records. The appearance of these records is similar to an LP, but they only contain one track each side.
