Melvins & Lustmord - Pigs of the Roman Empire (2004)

This 2004 Ipecac release is a collaboration between pre-grunge titans Melvins and industrial/noise wizard Lustmord (a.k.a. Brian Williams).

...look at Pigs of the Roman Empire as an exploratory effort along the lines of Sunn 0))), whose own path led from churning metal freakery to haunting middle-earth alchemy. (Taken from AMG)
