Power of Darkness

Power of Darkness is a demonstration album by the music production group Two Steps from Hell, originally released exclusively to clients in the motion picture and advertising industry for the purpose of licensing in March 2010. It was uniquely distributed on a flash drive, rather than a physical disc. It includes 32 principal tracks, split into two themed volumes. Additionally, it contains a large collection of alternative versions; therefore, in total, Power of Darkness consists of 77 tracks. They are composed by Thomas J. Bergersen and Nick Phoenix. The album was recorded in Prague, Czech Republic (by Capellen Orchestra), in Los Angeles, and in Utah, United States. The cover artwork and the sleeve are designed by Steven R. Gilmore.

Some tracks were made available to the general public on subsequent commercial albums, starting with Invincible (2010). In 2017, the album was finally released to the public, albeit modified to consist of only tracks which had still not yet been made commercially available and under the title of Power of Darkness Anthology.
