Adam Lambert has locked in a December 6 release date for his "Acoustic Live!" EP of five songs.

"Acoustic Live!" will feature unplugged versions of four songs from Lambert's 2009 debut album, "For Your Entertainment" -- "Whataya Want From Me," "Music Again," "Aftermath" and "Soaked" -- along with a stripped-down cover of Tears for Fears' "Mad World," -- one of the standout numbers he performed last year on the "American Idol" singing contest.

In a recent interview overseas, Lambert said he recorded the material for "Acoustic Live!" while touring and doing promotional appearances for "For Your Entertainment."
