In this youtube vid there's this rock version of the metal gear theme that starts at 8:13. I've been looking here and there but I don't know what the name is or where to get it. If you got the song or any info on where I can get it, that'd be awesome.

metal gear solid 2 substance soundtrack has a very similar track to that.
