Life and Death

 is Track 11 on the Xenosaga THE ANIMATION Original Soundtrack. It plays in the following scenes:
 * The Woglinde goes down in Episode 2.
 * KOS-MOS begins to communicate with the Elsa crew in Episode 3 (recap).
 * Jr. introduces the party to the half-Gnosified humans aboard the Durandal in Episode 5.
 * Wilhelm and Helmer communicate in Episode 7.
 * Shion disarms KOS-MOS's Subconscious Domain protection in Episode 8.
 * Helmer and Gaignun communicate as the population of Second Miltia watches the Proto Merkabah in Episode 12.

The melody at 0:13 (and later throughout the piece) is based upon a motif from Xenosaga Main Title.
