A few years before Trent's current masterwork The Fragile, he made an album we all know as The Downward Spiral. It was dark, emotional, but it was musical genius. He made an album that perfectly personifies anger, torment, and hatred. There are not many modern artists that can do that on one album(let alone two albums). Like I said, this is NIN's most essential album, so quit reading this and get it.
