He finally gives himself a break on "The Great Below," dropping the key from A to A-flat. The band is tight, and it SHOULD be, since most of the songs are at least half-mechanized. Here again, I've gotta praise the mixing - the instruments and keyboard tracks are distinct and crystal-clear. If you're even reading this review, you're probably familiar with NIN's songs. On the off chance you've lived on Blarrgon VI since 1989: industrial rock with influences as diverse as David Bowie and Einsturzende Neubauten. Let the It's Not Industrial debate begin! DISC 2: This is a real departure from any prior CD. It's like "A Private Evening With Trent Reznor." His gentler songs, with mostly piano and his voice. Very intimate. He throws in a couple of new pieces that don't really tell you where he's going with the next album, but they have an intriguing movie soundtrack quality. Get the double CD. Don't cheat yourself out of his "softer side" on the bonus disc. "All That Could Have Been" offers complete atonement for the half dozen or so lame "remix" haloes Reznor has put out over the years. All in all, this is a necessary addition to any NIN library. Besides, it's Halo Seventeen; the haloholics know what I'm talking about.
