Song of Nephilim (XS1 music)

Song of Nephilim is Disc 2, Track 11 on the Xenosaga Original Soundtrack and Disc 1, Track 14 on the album. It was remixed for the music of Xenosaga Episode II as and for the music of Xenosaga Episode III as Song of Nephilim (Xenosaga III ver.).

Trivia

 * The first four notes of Song of Nephilim are almost identical to the first four notes of the Dies Irae, a Gregorian chant often used as a motif in classical and modern music signifying death. (The Xenosaga II and Xenosaga III versions of this track are even more similar to the chant, with the first four notes being identical to those of the Dies Irae and an added phrase that matches the second phrase of the chant.)
