Singer Adam Lambert are invariably grateful for that creative freedom he or she is given whenever he collaborates with legendary rock-band Queen.

The 34-year-old has been working while using British rock gods since 2011, and embarked with a world tour together in 2014, with Adam singing the lead vocals made famous with the band’s original frontman, the late Freddie Mercury.

With such big shoes to fill, Adam was concerned about how his interpretation on the classic songs stomach across to fans and surviving bandmembers, Brian May and Roger Taylor, themselves, but thankfully, the musicians are already incredibly supportive.

“I loved using the services of them,” he told Billboard. “They are classy and inspiring with given me a large amount of freedom from the music, which I’m very grateful for.”

The new Queen and Adam Lambert European tour commences this summer (16) and Adam believes fans are usually in for a slight surprise once they discover which tracks from your band’s extensive back catalogue allow it to become onto their setlist.

“Roger and Brian have persuaded me into B-sides that I wasn’t accustomed to, usually are not knows what we’ll get into come early july,” he teased. “I’m sure there’ll be some surprises and stuff we’ve never done.”

In the mean time, Adam is centering on his own music along with a return to the show which made him famous, American Idol.

The singing contest is within its last ever season even though the star is grateful for that opportunity it gave him last year, he defintely won’t be mourning the show’s finale.

“It’s a stop of an era, Idol will usually go down in the past for what it really is and exactly what it did and what it really represents for anyone,” he explained. “It came long at the same time when I think we, as being a country, we was required to come together and we required to believe in something hopeful and offer underdogs the possibility and celebrate music as well as the diversity of music in this country. I think they did an admirable job, this is time to pack it.”
