A stone-cold classic. Actually I really like most of their stuff. Or "his" stuff, since that's practically a one-man band.

Ministry too, good call. "The Mind is a Terrible Thing to Taste" is their high water mark for me - it's after they fully became industrial metal (and not industrial/dance or /pop like they were early on), but before they became a little more digestible. I know a lot of people love "Psalm 69" best and it was certainly very popular, as well as having some awesomely crunchy guitar riffs. But for me "Mind" is their perfect album - creepy, atmospheric, disturbing, yet heavy as hell.

Then that leads into rockier waters like Skinny Puppy and Throbbing Gristle, but at that point it really has nothing to do with metal at all.
