Question: In what year was the death of the person who wrote the song Seven Seas of Rhye?

full_context: Document 1: Queen (band): By 1976, Queen were back in the studio recording A Day at the Races, which is often regarded as a sequel album to A Night at the Opera. It again borrowed the name of a Marx Brothers movie, and its cover was similar to that of A Night at the Opera, a variation on the same Queen Crest. The most recognisable of the Marx Brothers, Groucho Marx, invited Queen to visit him in his Los Angeles home in March 1977; there the band thanked him in person, and performed "'39" a cappella. Musically, A Day at the Races was by both fans' and critics' standards a strong effort, reaching number one in the UK and Japan, and number five in the US. The major hit on the album was "Somebody to Love", a gospel-inspired song in which Mercury, May, and Taylor multi-tracked their voices to create a 100-voice gospel choir. The song went to number two in the UK, and number thirteen in the US. The album also featured one of the band's heaviest songs, May's "Tie Your Mother Down", which became a staple of their live shows.
Document 2: Queen (band): Innuendo was released in early 1991 with an eponymous number 1 UK hit and other charting singles including, "The Show Must Go On". Mercury was increasingly ill and could barely walk when the band recorded "The Show Must Go On" in 1990. Because of this, May had concerns about whether he was physically capable of singing it. Recalling Mercury's successful performance May states; "he went in and killed it, completely lacerated that vocal". The rest of the band were ready to record when Mercury felt able to come in to the studio, for an hour or two at a time. May says of Mercury: “He just kept saying. 'Write me more. Write me stuff. I want to just sing this and do it and when I am gone you can finish it off.’ He had no fear, really.” The band's second greatest hits compilation, Greatest Hits II, followed in October 1991, which is the eighth best-selling album of all time in the UK and has sold 16 million copies worldwide.
Document 3: Queen (band): Brian May and Roger Taylor performed together at several award ceremonies and charity concerts, sharing vocals with various guest singers. During this time, they were billed as Queen + followed by the guest singer's name. In 1998, the duo appeared at Luciano Pavarotti's benefit concert with May performing "Too Much Love Will Kill You" with Pavarotti, later playing "Radio Ga Ga", "We Will Rock You", and "We Are the Champions" with Zucchero. They again attended and performed at Pavarotti's benefit concert in Modena, Italy in May 2003. Several of the guest singers recorded new versions of Queen's hits under the Queen + name, such as Robbie Williams providing vocals for "We Are the Champions" for the soundtrack of A Knight's Tale (2001).
Document 4: Queen (band): In 1973, Queen signed to a deal with Trident / EMI. By July of that year, they released their eponymous debut album, an effort influenced by heavy metal and progressive rock. The album was received well by critics; Gordon Fletcher of Rolling Stone called it ``superb '', and Chicago's Daily Herald called it an`` above average debut''. However, it drew little mainstream attention, and the lead single ``Keep Yourself Alive ''sold poorly. Retrospectively, it is cited as the highlight of the album, and in 2008 Rolling Stone ranked it 31st in the`` 100 Greatest Guitar Songs of All Time'', describing it as ``an entire album's worth of riffs crammed into a single song ''. The album was certified gold in the UK and the US.
Document 5: Queen (band): On 25 and 26 April, May and Taylor appeared on the eleventh series of American Idol at the Nokia Theatre, Los Angeles, performing a Queen medley with the six finalists on the first show, and the following day performed "Somebody to Love" with the 'Queen Extravaganza' band. Queen were scheduled to headline Sonisphere at Knebworth on 7 July 2012 with Adam Lambert before the festival was cancelled. Queen's final concert with Freddie Mercury was in Knebworth in 1986. Brian May commented, "It's a worthy challenge for us, and I'm sure Adam would meet with Freddie's approval." Queen expressed disappointment at the cancellation and released a statement to the effect that they were looking to find another venue. It was later announced that Queen + Adam Lambert would play two shows at the Hammersmith Apollo, London on 11 and 12 July 2012. Both shows sold out within 24 hours of tickets going on open sale. A third London date was scheduled for 14 July. On 30 June, Queen + Lambert performed in Kiev, Ukraine at a joint concert with Elton John for the Elena Pinchuk ANTIAIDS Foundation. Queen also performed with Lambert on 3 July 2012 at Moscow's Olympic Stadium, and on 7 July 2012 at the Municipal Stadium in Wroclaw, Poland.
Document 6: Queen (band): Before forming Queen, Brian May and Roger Taylor had played together in a band named Smile. Freddie Mercury (then known by his birth name of Farrokh "Freddie" Bulsara) was a fan of Smile and encouraged them to experiment with more elaborate stage and recording techniques. Mercury joined the band in 1970, suggested "Queen" as a new band name, and adopted his familiar stage name. John Deacon was recruited prior to recording their eponymous debut album in 1973. Queen first charted in the UK with their second album, Queen II, in 1974, but it was the release of Sheer Heart Attack later that year and A Night at the Opera in 1975 which brought them international success. The latter featured "Bohemian Rhapsody", which stayed at number one in the UK for nine weeks and popularised the music video. Their 1977 album, News of the World, contained "We Will Rock You" and "We Are the Champions", which have become anthems at sporting events. By the early 1980s, Queen were one of the biggest stadium rock bands in the world. Their performance at 1985's Live Aid is ranked among the greatest in rock history by various music publications, with a 2005 industry poll ranking it the best. In 1991, Mercury died of bronchopneumonia, a complication of AIDS, and Deacon retired in 1997. Since then, May and Taylor have occasionally performed together, including with Paul Rodgers (2004–09) and with Adam Lambert (since 2011). In November 2014, Queen released a new album, Queen Forever, featuring vocals from the late Mercury.
Document 7: Queen (band): Queen's popularity was stimulated in North America when "Bohemian Rhapsody" was featured in the 1992 comedy film Wayne's World. Its inclusion helped the song reach number two on the Billboard Hot 100 for five weeks in 1992 (it remained in the Hot 100 for over 40 weeks), and won the band an MTV Award at the 1992 MTV Video Music Awards. The compilation album Classic Queen also reached number four on the Billboard 200, and is certified three times platinum in the US. Wayne's World footage was used to make a new music video for "Bohemian Rhapsody", with which the band and management were delighted.
Document 8: Queen (band): The band had a number of bass players during this period who did not fit with the band's chemistry. It was not until February 1971 that they settled on John Deacon and began to rehearse for their first album. They recorded four of their own songs, "Liar", "Keep Yourself Alive", "The Night Comes Down" and "Jesus", for a demo tape; no record companies were interested. It was also around this time Freddie changed his surname to "Mercury", inspired by the line "Mother Mercury, look what they've done to me" in the song "My Fairy King". On 2 July 1971, Queen played their first show in the classic line-up of Mercury, May, Taylor and Deacon at a Surrey college outside London.
Document 9: Queen (band): In 1997, Queen returned to the studio to record "No-One but You (Only the Good Die Young)", a song dedicated to Mercury and all those that die too soon. It was released as a bonus track on the Queen Rocks compilation album later that year. In January 1997, Queen performed "The Show Must Go On" live with Elton John and the Béjart Ballet in Paris on a night Mercury was remembered, and it marked the last performance and public appearance of John Deacon, who chose to retire. The Paris concert was only the second time Queen had played live since Mercury's death, prompting Elton John to urge them to perform again.
Document 10: Queen (band): Queen are a British rock band formed in London in 1970. Their classic line-up was Freddie Mercury (lead vocals and piano), Brian May (lead guitar and vocals), Roger Taylor (drums and vocals) and John Deacon (bass guitar). Their earliest works were influenced by progressive rock, hard rock and heavy metal, but the band gradually ventured into more conventional and radio-friendly works by incorporating further styles, such as arena rock and pop rock.
Document 11: Queen (band): In 1978, the band released Jazz, which reached number two in the UK and number six on the Billboard 200 in the US. The album included the hit singles "Fat Bottomed Girls" and "Bicycle Race" on a double-sided record. Queen rented Wimbledon Stadium for a day to shoot the video, with 65 naked female models hired to stage a nude bicycle race. Reviews of the album in recent years have been more favourable. Another notable track from Jazz, "Don't Stop Me Now", provides another example of the band's exuberant vocal harmonies.
Document 12: Queen (band): In 1963, the teenage Brian May and his father custom-built his signature guitar Red Special, which was purposely designed to feedback. Sonic experimentation figured heavily in Queen's songs. A distinctive characteristic of Queen's music are the vocal harmonies which are usually composed of the voices of May, Mercury, and Taylor best heard on the studio albums A Night at the Opera and A Day at the Races. Some of the ground work for the development of this sound can be attributed to their former producer Roy Thomas Baker, and their engineer Mike Stone. Besides vocal harmonies, Queen were also known for multi-tracking voices to imitate the sound of a large choir through overdubs. For instance, according to Brian May, there are over 180 vocal overdubs in "Bohemian Rhapsody". The band's vocal structures have been compared with the Beach Boys, but May stated they were not "much of an influence".
Document 13: Bohemian Rhapsody: Starting with the A Day at the Races Tour in 1977, the band adopted their lasting way of playing the song live. The opening ballad would be played on stage, and after Brian May's guitar solo, the lights would go down, the band would leave the stage, and the operatic section would be played from tape, while coloured stage lights provided a light show based around the voices of the opera section. A blast of pyrotechnics after Roger Taylor's high note on the final ``for me ''would announce the band's return for the hard rock section and closing ballad. Queen played the song in this form all through the Magic Tour of 1986. This style was also used for the Freddie Mercury Tribute Concert, with Elton John singing the opening ballad and then after the taped operatic section, Axl Rose singing the hard rock section. John and Rose sang the closing ballad part together in a duet.
Document 14: Queen (band): At the end of 2004, May and Taylor announced that they would reunite and return to touring in 2005 with Paul Rodgers (founder and former lead singer of Free and Bad Company). Brian May's website also stated that Rodgers would be "featured with" Queen as "Queen + Paul Rodgers", not replacing Mercury. The retired John Deacon would not be participating. In November 2004, Queen were among the inaugural inductees into the UK Music Hall of Fame, and the award ceremony was the first event at which Rodgers joined May and Taylor as vocalist.
Document 15: Queen (band): The group's second LP, Queen II, was released in 1974, and features rock photographer Mick Rock's iconic image of the band on the cover. This image would be used as the basis for the 1975 "Bohemian Rhapsody" music video production. The album reached number five on the British album chart and became the first Queen album to chart in the UK. The Freddie Mercury-written lead single "Seven Seas of Rhye" reached number ten in the UK, giving the band their first hit. The album is the first real testament to the band's distinctive layered sound, and features long complex instrumental passages, fantasy-themed lyrics, and musical virtuosity. Aside from its only single, the album also included the song "The March of the Black Queen", a six-minute epic which lacks a chorus. The Daily Vault described the number as "menacing". Critical reaction was mixed; the Winnipeg Free Press, while praising the band's debut album, described Queen II as a "over-produced monstrosity". Allmusic has described the album as a favourite among the band's hardcore fans, and it is the first of three Queen albums to feature in the book 1001 Albums You Must Hear Before You Die.
