Aliens vs. Predator: Requiem (soundtrack)
Aliens vs. Predator: Requiem – Original Motion Picture Soundtrack is the official soundtrack album of the 2007 science fiction film Aliens vs. Predator: Requiem. It was composed and conducted by Brian Tyler and released on December 11, 2007, by Varèse Sarabande and Fox Music. The score is completely orchestral and incorporates several themes from both the Alien and Predator franchises. Background
The film's main theme track is a clash of two main themes, one consisting of the Predator type theme (bongos and basses) and the second of the Aliens (high pitched violins, violas and flutes). The directors Greg and Colin Strause wanted to take a new direction from Harald Kloser's Alien vs. Predator score and wanted Tyler to use some reference to the three films' original score pieces, such as the horrific violas and percussion from James Horner's Aliens and the primitive tribal percussion from Alan Silvestri's Predator and Predator 2. Tyler also referenced composers Elliot Goldenthal's Alien 3 and John Frizzell's Alien Resurrection into the score. Track listing
