FDtS is a remix album featuring songs from The Downward Spiral (1994) in various guises and states of deconstruction. Some are chaotic, resembling the original with extra layers of electronic distortion and intensity, while others get wedded to dance beats that aren't as lazy or awful as it sounds in words. If you're familiar with TDS, then you'll be picking out recognisable moments, and engaging or scratching your head at new ones. It's a hypnotic deluge of fractured emotions that's impossible for me to define accurately.
The US version has a number of different tracks than the rest of the world, and vice versa. I own both but prefer the non-US version.
