}}This is the third track on the Quake Soundtrack, and features layers of [[Trent Reznor]] whispering, played backwards, throughout the track. A single-note bassline undulates beneath while uneasy synthesizer chords fade in and out. Later, percussion loops and distorted guitar riffs are layered on top.
