They were quite a thrilling and action packed Swedish death metal band that featured members From Dismember and Michael Ammott (spelled properly?). That guy I just mentioned and I'm not sure if that's his name or not would go on to Gothenburg superstars Arch Enemy.
Well Carnage had one album called Dark Recollections in 1990. They had a few demos before that and on one of those demos, they were grindcore. They evolved into death metal which is cool.
