Queen are a British rock band formed in London in 1971 and one of the most commercially successful musical acts of all time. The group originally consisted of Freddie Mercury, (lead vocals), Brian May (lead guitar, vocals), John Deacon (bass guitar), and Roger Taylor (drums, vocals).
Queen's initial works were chiefly glam rock, heavy metal and progressive rock orientated, however with time the band incorporated diverse and innovative styles in their music, exploring the likes of vaudeville, electronic music and funk.
The band digressed from using progressive themes in their music in the mid-1970s, with more conventional and radio-friendly works bringing them greater success. Throughout the 1970s, Queen disclosed the absence of synthesisers on their albums, yet their style continued to evolve. They eventually started using synthesisers in the 1980s, reflecting their experimental approach to music.
