I'm really looking foward to the noise in it. They apparently were going for the "Ambient background noise" like quake, rather than actual music, and although Trent Reznor backed out :(, The sounds are being done by Chris Vrenna :) (former drummer and co-founder of Nine Inch Nails and scorer of American Mcgee's Alice, which was incredible)
There was another guy helping Chris out. i cant remember his name (and I am too lazy to look it up right now) but he is another member of Tweaker and has played for a ton of other bands. :) i cant wait.
Sing on over to
