Queen + Adam Lambert is a collaboration between the 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. The collaboration originated when May and Taylor appeared on American Idol in 2009 when Lambert was a contestant. They began performing occasionally in 2011, conducted a short European tour in 2012, and in 2014 announced a world tour, the Queen + Adam Lambert Tour 2014–2015 with dates in North America, Australia, New Zealand, Asia, Europe and South America. In the summer of 2016, the group performed several dates as part of a festival tour in Europe and several dates in Asia. The next year, the group announced a second worldwide tour scheduled for 2017 and 2018.
Joining May, Taylor and Lambert are long-time Queen touring keyboardist Spike Edney, bassist Neil Fairclough and percussionist Tyler Warren. Although there are currently no plans to release a studio album with this lineup, May and Taylor have stated that there is a possibility of the group recording original material.
