Adam Lambert and British rock group Queen will perform together at four concert dates this summer.

While a July 7 performance at Sonisphere 2012 was canceled, four dates are currently planned.

Queen currently includes guitarist Brian May and drummer Roger Taylor. Taylor and May formed the band Smile, which Freddie Mercury altered to Queen when he joined. Mercury died in 1991 of complications due to AIDS.

According to music glossy Billboard, Lambert and Queen will perform together at a June 30 show in Moscow's Olympic Arena, and a show with Elton John is also under consideration. They'll also perform two shows in July at the Hammersmith Apollo to provide “some alternative … for some of the the people who had bought tickets” to the now-canceled Sonisphere date, Taylor told Billboard.

Taylor added that Lambert fits the group's “theatricality.”

“We're really excited about it,” Taylor said. “Adam … of course he has this unbelievable range, like Freddie had range. Adam can really cover it. He's an extraordinary singer and a real talent. I feel he fits into our sort of theatricality.”
