Queen are a British rock band that formed in London in 1970. Their classic line-up was Freddie Mercury (lead vocals, piano), Brian May (lead guitar, vocals), Roger Taylor (drums, vocals), and John Deacon (bass guitar). Queen's 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, into their music.
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.
The band have released a total of 18 number one albums, 18 number one singles, and 10 number one DVDs. Estimates of their record sales generally range from 150 million to 300 million records, making them one of the world's best-selling music artists. Queen received the Outstanding Contribution to British Music Award from the British Phonographic Industry in 1990. They were inducted into the Rock and Roll Hall of Fame in 2001.
