Adam Lambert is walking away from RCA Records -- and you won't believe why.

Lambert's label was looking for a concept album for the followup to 'Trespassing.' Namely, RCA wanted Lambert to record an entire album of 80's cover songs. However, Glamberts didn't like this idea at all, despite Lambert's cover of Tears for Fears' 'Mad World' being one of the best 'American Idol' renditions ever. Rumors grew louder when Lambert covered another Tears for Fears hit, 'Shout,' at his performance for the Trevor Project earlier this month.

Lambert is now leaving RCA due to "creative differences," which he revealed in an open letter to The Hollywood Reporter, who initially broke the story of the covers concept.

You can check out his full letter below.

Dear Shirley,

Thank you for your continued interest in, and support of, my musical career. After reading your article on July 8th, and seeing the very impassioned responses, I thought it would be good to write and let you know what is actually happening with my next album.

I've had an amazing few years working with the team at RCA; I admire all of them a great deal, and truly appreciate the energy & enthusiasm that went into making both "Trespassing" & "For Your Entertainment" successes.
That said, at this point, we are indeed having the oft-cited "creative differences" as to what my next project will be. Your article was correct, the label is "pushing for an (80's) covers album," and feels that this is the only kind of release they are prepared to support. While there are lots of great songs from that decade, my heart is simply not in doing a covers album.

Over the past four years, I have been truly fortunate to work with an amazing roster of producers, writers and engineers. Thanks to them, I have grown as both a songwriter and a vocalist. Artistically & professionally, I think it is essential that I continue with this evolution. I am already deep into writing new material with some very talented colleagues for a brand new album, and I can't tell you how excited I am to share this new sound & direction. This music is where my heart is, and I believe that is what my fans want to hear. So after careful consideration, I have made the decision to respectfully part ways with RCA. My passion for the music & respect for the fans will always come first. I am excited to find a new label team who shares this vision.


Hopefully Lambert will have more creative control over his next project. And if you're really itching for more Lambert loveliness, just hold out til this fall when he appears on 'Glee!'
