Invincible may be a compilation of sorts what with only two then-new tracks, but that doesn't interfere with the level of engagement. If you're looking for music to become immersed in and feel motivated by, Two Steps from Hell deliver this in spades. And their tracks are brief, so you needn't worry about waiting to be inspired.
A superb example of movie trailer music at it's best, this album was the first public album by Two Steps From Hell and simply rocks!! Best songs include Heart of Courage (used in Frozen Planet trailers by the BBC & at the 2012 European Championship in Poland-Ukraine), as well as Protectors of the Earth & Tristan (used in Doctor Who trailers by the BBC).
