SIGNAL PRESSURE REVIEW
By late 1973, Berlin’s underground was starting to sound like its architecture—hard surfaces, low hums, and power surges. Spannungszone sits right at that shift. Recorded at the reinforced Studio K4 in Tempelhof, it unites three of the Intercommunal Signal Network’s most distinctive minds: Gernot Wolff (Klan der KdK engineer turned synth mechanic), Hennix Duval (MIRRORDEN’s low-frequency tactician), and Lucifer Mordant, freshly out of his Southern Italy exile phase, already mutating the idea of “guitarist” into “live fault in the circuit.”
The record opens with a metallic pulse and never quite relaxes. Kontaktfeld throws out steady percussive loops over chattering synth filters, while Duval’s tape-fed bass lurches like an engine trying to find idle. Mordant’s guitar cuts and feeds back in bursts, less solo than sabotage. Isobarische Drift slows the charge, a motorik half-groove anchored by machine claps and filtered drones. Magnetkörper ends Side A with a ten-minute burn—part rock improvisation, part voltage study—its final moments collapsing into pulse noise.
Flip it and Vektorlinie feels almost rhythmic, a proto-punk chug built from drum machine and bass echo. The title track Spannungszone is pure industrial minimalism: dueling oscillators modulate against Duval’s bass drone, tension stretched to the breaking point. Restpuls closes the LP with mechanical grace—a slow-release of rhythm into hiss, like the sound of a system powering down after a long session.
What keeps Spannungszone alive is its tactile energy. It’s not a sterile electronic experiment—it’s three musicians pushing voltage and tape until both start to sweat. The album’s clean edges mask something feral beneath, the sound of structure under pressure.
You can trace a lot of later European underground from this single record: the dry funk of early Neubauten, the mechanical trance of Heldon, even post-punk’s austerity. But here it’s all still raw, held together by discipline, duct tape, and static electricity.

EPILOGUE
Spannungszone captures the precise moment when Berlin’s underground hardened from commune psych into mechanical form. Wolff’s machines pulse like factory lungs; Duval’s bass provides ballast and repetition; Mordant’s feedback and voice cut across the signal with human static.
It’s equal parts control and collapse—discipline meeting noise at the voltage line. Released in 277 copies, it circulated quietly but left fingerprints everywhere: in early punk’s tight rhythms, in industrial’s sense of architecture, and in Aurora Weltklang’s own turn from free communal sound toward engineered tension.
Half a century later, it still sounds ready to short out the circuit.
