Thomas Jacob Bergersen (born July 4, 1980) is a Norwegian composer who is the co-founder of the trailer music production company called Two Steps From Hell and has written music for numerous high profile trailers.
He started his musical career as a demoscener, writing tracked modules under the name Lioz in the group Index. The release of a 2007 trance-genre single entitled "Remember September" saw Bergersen team with fellow Norwegian artist Boom Jinx.
In May 2010, he and his business partner, Nick Phoenix, released an initial public Two Steps From Hell album entitled Invincible, featuring some of his most popular tracks, including "Freedom Fighters", "Moving Mountains", "Heart of Courage", and others. Several additional commercial album releases have since followed, including Archangel and SkyWorld, each of which has charted on the iTunes top 10 in the Soundtracks category. Bergersen also performed in a 2013 live concert at the Walt Disney Concert Hall alongside Phoenix, confirming at least one future concert planned for Europe, intending to begin touring at some point in 2015.
