The title track lays it out best, its piledriving kicks and metallic squeaks warning anyone who dares drop a needle on this record. "Codex" is techno that could soundtrack a horror movie, though the duo never get campy or over-the-top. "Arise" gives its fist-pumping chord progression and powerful rhythm section a crunchy coat of grit, yet it's efficient and cleverly arranged. By the same token, "Melting," with its bounding drum pattern and conventional techno build, could've come out on Ostgut Ton.
With noisy growls that sound like a malfunctioning motor, "Realgar" finds Scalameriya & VSK at their dirtiest, though it's still marked by a certain sleight of hand. Across Codex, the producers are like muzzled dogs: they snap and bark but never bite. Though it lacks some of the typical Power Vacuum madness, this is a solid, functional techno record.
