Queen were an English rock band formed in 1970 in London by guitarist Brian May, lead vocalist Freddie Mercury, and drummer Roger Taylor, with bass guitarist John Deacon completing the lineup the following year. While it is uncertain how many albums the band has sold, estimations range from 130 million to over 300 million albums worldwide.

The band is noted for their musical diversity, multi-layered arrangements, vocal harmonies, and incorporation of audience participation into their live performances. Their 1985 Live Aid performance was voted the best live rock performance of all time in an industry poll.

Queen had moderate success in the early 1970s, with the albums Queen and Queen II, but it was with the release of Sheer Heart Attack in 1974 and A Night at the Opera the following year that the band gained international success. They have released fifteen studio albums, five live albums, and numerous compilation albums. Eighteen of these have reached number one on charts around the world.

Following Mercury's death in 1991 and Deacon's retirement later in the decade, May and Taylor have performed infrequently under the Queen name. Since 2005 they have been collaborating with Paul Rodgers, under the moniker Queen + Paul Rodgers.
