Invincible is the first public album by the group Two Steps From Hell, released in May 2010. It consists of 22 tracks written by composers Thomas J. Bergersen and Nick Phoenix. The tracks are a collection of fan favourites from prior demonstration albums previously only available to the industry, "represent[ing] the very best of Thomas and Nick’s first few years at Two Steps From Hell". Two tracks, however, are brand new compositions.
