Corpus Sonus opens with three remixes in a row — two from Plastique01, one from Tec.Nico — before FA:B's first Original Mix even shows up. That's an unusual running order: the record lets other hands define the entrance, then reveals the author's versions of those same three titles later in the list.
Plastique01 takes on "Lethe" and "Sehnsucht" and runs the same procedure on both: drop the tempo eight BPM from the original (142 to 134 on "Lethe," 140 to 132 on "Sehnsucht") and push both pieces toward related minor keys — Db Minor and Eb Minor, a whole step apart — regardless of the fact that "Lethe"'s original sits in a major key. That's a recognizable signature: two tracks with different harmonic starting points end up sounding like they belong to the same family.
Tec.Nico works "Eternal Tension" differently. The remix only shaves two BPM off the original (142 to 140) but rewrites the harmony entirely, from F Major to A Minor — not chasing distance from peak-time tempo, but recoloring the track without touching the pulse.
All three originals resurface later, each with its own tempo and key identity — "Lethe" in Db Major at 142, "Sehnsucht" in Bb Minor at 140, "Eternal Tension" in F Major at 142 — as if the tracklist wants the reinterpretations heard first, and the originals only after the context is set.
Somewhere in that back-and-forth, "Interlude" stands as the record's only track tagged Ambient / Experimental, landing right after the densest run of techno — a pocket of air before "Khaos," the album's fastest cut at 145 BPM, pushes the record to its hardest point.
Ten tracks, three names, and a running order that turns Corpus Sonus into a deliberate exercise in comparison rather than a simple stack of versions.
