Bone-crunching chaos to be sure, but chaos with heart, emotion, and intelligence. Those aren't qualities that mean much to narrow-minded fans of speed-metal, industrial, thrash or whatever else the flavor of the week is (all of whom will no doubt dis this review), but they are qualities associated with great art. This is great art. Trent Reznor's first and still best (Downward Spiral is the other must-have), whose career trajectory went on its own downward spiral with the unfocused and disappointing Fragile.
