Queen are a British rock band that formed in London in 1970. The classic line-up was Freddie Mercury (lead vocals, piano), Brian May (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.
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.
