Track 7 contains a hidden track (listed as 7C) after a period of silence (listed as 7B).
From the liner notes: "As an exercise in sample manipulatiom, DWM draws exclusively from source audio generated by swinging a cheap microphone in front of a misfiring heating unit, itself congested with the fibrous dust of advanced decrepitude and exhuming a near death-rattle from its fractured internal respiritory systems."
