Before forming Queen, Brian May and Roger Taylor had played together in a band named Smile. 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. Mercury joined the band in 1970, suggested "Queen" as a new band name, and adopted his familiar stage name. John Deacon was recruited prior to recording 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 popularised the music video. Their 1977 album, News of the World, contained "We Will Rock You" and "We Are the Champions", which have become anthems at sporting events. By the early 1980s, Queen were one of the biggest stadium rock bands in the world. Their performance at 1985's Live Aid is ranked among the greatest in rock history by various music publications, with a 2005 industry poll ranking it the best. In 1991, Mercury died of bronchopneumonia, a complication of AIDS, and Deacon retired in 1997. Since then, May and Taylor have occasionally performed together, including with Paul Rodgers (2004–09) and with Adam Lambert (since 2011). In November 2014, Queen released a new album, Queen Forever, featuring vocals from the late Mercury.
