The Doomstar Orchestra is the fully-orchestrated symphonic score to the Dethklok musical special Metalocalypse: The Doomstar Requiem. It was written by Brendon Small with arrangement assistance and production by Bear McCreary, who assembled and directed the 50-piece orchestra for the recording. The uninterrupted soundtrack version of the score runs 23:22 long, with some of the songs' representative sections being played in a slightly different order than they actually occur during the animated special and on the rest of the soundtrack itself. All sections of the orchestral recording can also be heard individually on the soundtrack within the arrangement of the respective tracks they were produced for, accompanying Dethklok's instruments and character vocals.
