I'm listening to Ministry's "The Land of Rape and Honey" right now, and for some reason I am reminded of hearing the album for the first time as a fifteen year old and thinking: "I didn't know anything this amazingly awesome existed in our musical universe." Between 1988 and now, I've probably listened to this album (or at least parts of it) well over a thousand times.
Even twenty years later, it still sounds fresh, its impact undiminished by years of subsequent "industrial" and "nu-metal" stuff that's come along in the years since.
If you've never heard it, you're in for quite a treat if you seek it out and listen to it now. And if you haven't given it a spin "in years," I highly recommend that you put it on right away and remember that once upon a time, what was called "industrial" music was angry and innovative (and like punk of yore, covered a lot of disparate musical ground, not just one single sound -- in the case of contemporary "industrial," it's four-on-the-floor dance beats for "dark ravers" and all else has disappeared or been reclassified).
