This is the original album version. Characteristic of the band's mid-90s industrial rock sound, it opens with an eerie and quiet machine-like sound collage [[samples|sampled]] from the film ''Leviathan'', which transitions into an imitative musical composition. The structure, repetitive in nature, contains three distinct but similar sections, all driven by machine-like percussion loops and undulating rhythm guitar and synthesized bass. A looped mechanical sound that runs through the song is sampled from the film ''Aliens'' (the opening scene immediately after the chamber is cut open.) The choruses reflect a brighter mood with prominent melodic synthesizers and glimpses of guitar. The three sections are joined by two quiet instrumental breaks, a technique used later on "[[Even Deeper]]." The ascending synth melody from 5:13 to 5:20 seems to be a reference to or an interpolation of "Laura Palmer's Theme" from the television show ''Twin Peaks''. During this same section, there is a looped sample of a woman saying, "Kirk, help?" from the film ''The Texas Chainsaw Massacre''. The "gong" sound that appears midway through the track and after the bridge is also used near the end of "[[Hurt (song)|Hurt]]", but the pitch is changed.
The drums used are the same as on "Fell From Heaven" by Lead Into Gold (a Paul Barker side-project, and one whose music video for "Faster Than Light" features a cameo from Reznor.) This may be strictly coincidence, given that some of the same or similar instruments may have been used, or it could be an actual sample.
