I got into NIN with Further Down The Spiral (UK, so v2 with Heresy and Ruiner versions). This was probably around late 1995 up to mid-1996.

It was several years later that I picked up The Downward Spiral. Listening to the original versions of the songs was a very odd, uncomfortable, exhilarating experience. It felt like I was listening to the best remix album I'd ever heard.
