===Claustrophobia Machine (Raw)===
This is the only known version. It is similar to "[[Underneath It All]]" and "[[Somewhat Damaged]]" in that it is a percussion-driven piece. The track is harsh, beginning with a steady kick along with a wire-like sound that persist through the entire song. As the piece carries on, other sounds are added and removed (including a heavy bass, a particularly sharply mixed snare, and cymbals), a beat drum track forming after a while that continues to be layered upon, growing more intense until finally being suddenly removed, leaving the kick and wire once more before the song ends abruptly.
