Last month, Queen + Adam Lambert wrapped up their 2014 concert dates in New Zealand, following a summer trek across North America, Asia and Australia.

Queen first teamed up with Lambert in 2009 to perform the band's anthem, "We Are The Champions", on American Idol's season 8 finale. The pairing partnered again in 2011 at the MTV European Music Awards in Belfast. In the summer of 2012 they performed their first live concerts together with three sold-out shows in the UK at London's Hammersmith Apollo as well as concert appearances in Russia, Ukraine and Poland. "We have a very interesting set design," says guitarist Brian May. "It's big and daring. We're going to do it to the max."

"Each time we've worked with Adam with our music, he's just the most incredible front man," adds drummer Roger Taylor. "He's sensational. He has this amazing range, 'cause Freddie [Mercury] had a great range. Adam can really cover it. He's an extraordinary singer and a real talent. I feel he fits into our sort of theatricality. It is very comfortable."
