Song of Nephilim (Xenosaga III ver.)

 is a track in Xenosaga II to III: A Missing Year and Xenosaga Episode III. It is a remix of from the Xenosaga II: Jenseits von Gut und Böse ~Movie Scene Soundtrack~, and by extension, of  from the Xenosaga Original Soundtrack. It also contains a melody based upon that of my long forgotten cloistered sleep (unreleased work of Xenosaga) at 1:07.

It plays in the following instances:

 * Almadel realises she's been given someone else's memories while the Song of Nephilim starts playing in Chapter 5.

Trivia
Like and (to a lesser extent), Song of Nephilim (Xenosaga III ver.) is based upon the Dies Irae, a Gregorian chant often used as a motif in classical and modern music to signify death.
