The compilation will include three American Idolperformances from when he was on the show, including his covers of "Mad World" by Tears for Fears and "One" by U2. Lambert's version of Lady Gaga's "Marry the Night" from his appearance on "Glee" closes out the 14-track CD.
Also included on the record: Lambert's contribution to the 2012 film, 2012, "Time for Miracles."
"If some of these tracks feel like musical mission statements, it's in their skillful fusion of mainstream pop and rock with left-of-center, if not underground, musician and pop-cultural markers, and their clear conviction towards that mission," reads the album's liner notes. "And it that's not the hallmark of an artist who's unfailingly true to himself... well, you are invited to listen to some more until you get it."
Lambert walked away from his recording contract with RCA last July after the release of two albums, 2012's "Trespassing" and 2009's "For Your Entertainment," along with several EP's and a live collection.
