This is the original album version. Its descending, filtered guitar introduction begins immediately as "Starfuckers, Inc." ends, and is augmented by a drum loop before opening up into the main body of the song, characterised by a catchy bassline, Reznor's wordless background vocals, and a guitar solo. The final section of the song seems to be a noise loop made by guitars, which crossfades with either "I'm Looking Forward To Joining You, Finally" (CD) or "The New Flesh" (vinyl).
Complication (Alternate Version)
Released on The Fragile: Deviations 1. Also known as "Complication" (Alt) when it was originally released on Apple Music as part of The Fragile Instrumental. Same as the album version, but with an extended ending.
Complications Of The Flesh
Danny Lohner created this mashup of "Complication" and "The New Flesh." It appears exclusively on Part 3 of the We're In This Together single.
Complication (And All That Could Have Been)
This live version appears only on the DVD and VHS releases of And All That Could Have Been.
On the Fragility 2.0 tour, three large screens are dropped down behind the band, showing lights and shapes that seem to respond to the music.
