Yeah, that right there is actually a collaboration remix of an epic Star Wars song (from movies some might say are not that good, though I quite enjoyed them). This remix features the Duel of the Fates, composed by the incredibly renowned Star Wars music composer John Williams. Duel of the Fates is a single from the Star Wars Episode I: The Phantom Menace soundtrack, which is one of six soundtracks for each six movies. The Star Wars soundtracks contain some of the most well-known modern film music.
In the first episode of Star Wars, The Phantom Menace, this single debuted in the last lightsaber duel between the evil Sith Lord Darth Maul, and the masterful Jedi Qui-Gon Jinn (with the aid of his well-known apprentice, Obi-Wan Kenobi). The music rises and falls with the tides of the battle, and accompanies the final scenes in the movie with Qui-Gon Jinn.
This particular remix is done by The Noisy Freaks and Dead C∆T Bounce, whose Facebook pages can be found here and here, respectively.
