It really sounds like a Godflesh or a Scorn demo. Well, the people in the band at the time did go on to one or both of those bands. There are plenty of groans and screams inserted almost whenever they felt like it, it's entirely rhythm section playing the same steady beat and bass riff over and over again and there's, like, no guitars at all. Very primal. Actually there's one bit of flashiness, the fill near the end (3:38) but that's it. UGH!
