Problem: Background: 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.
Context: 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.
Question: what is the trilogy?
Answer: 1972 saw the start of increasing line-up disruption for Gong.

Problem: Background: Gloria Estefan (nee Fajardo; born September 1, 1957) is a Cuban-American singer, songwriter, actress, and businesswoman. She started off her career as the lead singer in the group called "Miami Latin Boys" which was eventually known as Miami Sound Machine. Estefan's breakthrough success with "Conga" in 1985 made her known worldwide. The song became Estefan's signature song and led to the Miami Sound Machine winning the grand prix in the 15th annual Tokyo Music Festival in 1986.
Context: Starting in 1977, Miami Sound Machine began recording and releasing various albums and 45s on the Audiofon Records label in Miami. The first album from 1977 was entitled Live Again/Renacer and was released with two different covers. After several more releases on the Audiofon label as well as the RCA Victor label and Miami Sound Machine's own label MSM Records, the band was signed to Discos CBS International and released several albums, 45s, and 12"s beginning with the 1978 self-titled album Miami Sound Machine. Growing in popularity in both the U.S. and around the world, the group would continue recording and issuing various works for Discos CBS International through 1985. In 1984, Miami Sound Machine released their first Epic/Columbia album, Eyes of Innocence, which contained the dance hit "Dr. Beat" as well as the ballad "I Need Your Love". Their more successful follow-up album Primitive Love was released in 1985 launching three Top 10 hits on the Billboard Hot 100: "Conga" (U.S. No. 10), "Words Get in the Way" (U.S. No. 5), and "Bad Boy" (U.S. No. 8), as well as "Falling in Love (Uh-Oh)" (U.S. No. 25) which became follow up hits in the U.S. and around the world. "Words Get in the Way" reached No. 1 on the US Hot Adult Contemporary Tracks chart, establishing that the group could perform pop ballads as successfully as dance tunes. The song "Hot Summer Nights" was also released that year and was part of the film Top Gun. Their next album, 1987's Let It Loose, went multi-platinum, with three million copies sold in the US alone. It featured the following hits: "Anything for You" (No. 1 Hot 100), "1-2-3" (No. 3 Hot 100), "Betcha Say That" (No. 36 Hot 100), "Rhythm Is Gonna Get You" (No. 5 Hot 100), and "Can't Stay Away from You" (No. 6 Hot 100). "Can't Stay Away From You", "Anything for You", and "1-2-3" were all No. 1 Adult Contemporary hits as well. In that same year, Estefan took top billing and the band's name changed to Gloria Estefan and Miami Sound Machine. In 1989, the group's name was dropped, and Estefan has been credited as a solo artist ever since. In 1988, after the worldwide chart success of single "Anything for You", her Let it Loose album was repackaged as Anything for You.
