Trent Reznor of Nine Inch Nails has never been shy about encouraging others to remix his music. His 1992 EP, Broken was quickly followed by a collection of remixes called Fixed and his next two albums, The Downward Spiral and The Fragile), each had their own companion remix albums (Further Down the Spiral and Things Falling Apart, respectively). These days, when every artist with a modicum of dance-floor appeal commissions remixes from high-profile producers to help tap into a cross-over market, this may seem pedestrian, but in the early ’90s this was unheard of from mainstream acts, and far from being uninspired club mix rehashes, many of the tracks on these albums were complete transformations, twisting Reznor’s creations into strange, unrecognizable creatures.
