Queen + Adam Lambert is a collaboration between the remaining active members of the British band Queen and American vocalist Adam Lambert. As with all other Queen performances since 1997, longstanding bassist John Deacon has declined to participate in the project due to his retirement. This is the first long-term collaboration of Queen since the Queen + Paul Rodgers project ended in 2009. Like the previous project, it was made clear that Lambert would not be replacing Queen frontman Freddie Mercury, but rather that he would be featured with the band's active members.

Roger Meddows Taylor is an English musician, songwriter and record producer. He achieved international fame as the drummer and backing vocalist for the rock band Queen. As a drummer, Taylor was recognised early in his career for his unique sound and was voted the eighth-greatest drummer in classic rock music history in a listener poll conducted by Planet Rock in 2005. He was inducted into the Rock and Roll Hall of Fame in 2001 as a member of Queen.
