Queen est un groupe de rock qui a formé en 1970 dans Londres. La bande consiste de Freddie Mercury, Brian May et Roger Taylor. Brian May et Roger Taylor étaient dans le groupe Smile.
Before joining Queen, Brian May and Roger Taylor had been playing together in a band named Smile with bassist Tim Staffell. 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 after Staffell's departure in 1970. Mercury himself joined the band shortly thereafter, changed the name of the band to "Queen", and adopted his familiar stage name. John Deacon was recruited prior to recording their eponymous debut album in 1973. Queen enjoyed success in the UK with their debut and its follow-up, Queen II in 1974, but it was the release of Sheer Heart Attack later in 1974 and A Night at the Opera in 1975 that gained the band international success. The latter featured "Bohemian Rhapsody", which stayed at number one in the UK Singles Chart for nine weeks; it charted at number one in several other territories, and gave the band their first top ten hit on the US Billboard Hot 100. Their 1977 album, News of the World, contained two of rock's most recognisable anthems, "We Will Rock You" and "We Are the Champions".
