Queen enjoyed success in the UK in the early to mid-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. Since Mercury's death and Deacon's retirement, May and Taylor have performed infrequently together at special events and programmes as members of other ensembles. Between 2004 to 2009 the duo collaborated with Paul Rodgers under the moniker Queen + Paul Rodgers.
