Genesong

Genesong is the eighteenth and final track included in the first disc of the Halo 2 Anniversary Original Soundtrack. It is a new rendition of Reclaimer from the Halo 2: Original Soundtrack, and once again features Steve Vai as a soloist. Unyielding, which served as a basis for Reclaimer, is missing from the remastered album.
