Hey,
Somebody over at YouTube finally found the name of the song that plays in the Gilgamesh trailer.
For those interested, it's called Never Rest and it's by a group called Royal Lush.
I know KMC and a few others were wondering about it too, so I just thought I'd let you all know. You can listen to the full song and others from Royal Lush on their official MySpace site:
