Queen are a British rock band that 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, into their music.
Before forming Queen, May and Taylor had played together in the band Smile. Mercury, then known by his birth name, Farrokh Bulsara, was a fan of Smile and encouraged them to experiment with more elaborate stage and recording techniques. Mercury joined in 1970, suggested the name “Queen”, and adopted his familiar stage name. Deacon was recruited before the band recorded 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 also helped to popularise the music video.
