You thought techno was safe? Think again. With Unreleased Techno Loops 2021–2023, Ruprecht 4500 grabs the genre by the throat and throws it into a blender set to “war mode.” Spearheaded by Sigfrid — the same lo-fi wizard behind Bergënot and Kellersynth — this project explodes across genres, bringing together gabber brutality, makina absurdity, acid squelch, and twisted DIY techno loops pulled from the depths of his hard drive.

This isn’t club-ready EDM. It’s post-industrial body horror in loop form. Tracks glitch, distort, slam, and stutter like they’re being played on melted hardware. There’s structure here, sure, but it’s constantly on the edge of meltdown — tempos push 180+, acid lines twist like possessed circuit boards, and every sound feels one bad cable away from collapse.

The aesthetic is proudly raw: this is CDr culture, not Spotify-core. Each loop feels like it was built on broken gear in a bunker with flickering lights and no heat. But that’s the magic — these tracks don’t follow trends, they carve out weird rave rituals in pure underground fashion. Whether you’re a gabber head, an acid freak, or a metalhead with a taste for bizarre electronica, this release speaks the universal language of noise and rhythm.

Released on Halloween 2023 via Moos und Efeu Produktionen — the same label pushing Tänzelcore and other outsider electronic visions — this digipak CDr is a limited, cult-ready artifact from a world that’s half-digital nightmare, half analog rave resurrection. Throw it on, crank the volume, and get ready to sweat through the walls.
