Adam Lambert has had a whirlwind career since coming in second place on season eight of 'American Idol,' and it seems he's got more success to look forward to in the near future.

The Grammy-nominated singer, fresh off his 'Glam Nation' tour with fellow 'AI' alum Allison Iraheta, is gearing up for the release of his live tour DVD with a live version of his '80s-inspired breakup ballad 'Sleepwalker' off his 2009 album 'For Your Entertainment.'

Lambert says of the guitar-heavy rock track, "This song is about getting your heart broken. It sucks at the time, but I believe you don't know true love, unless you know true heartache."
