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 the following year's A Night at the Opera that the band gained international commercial and critical success--those albums, along with Queen II, have been cited as being among Queen's best work and some of the finest albums ever recorded. They have released fifteen studio albums, five live albums, twelve compilation albums, and nine DVDs. Since Mercury's death in 1991 and Deacon's subsequent 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.
