Einsturzende Neubauten harvested punk rock from the weed patches, trespasser graves and broken concrete that surrounded the Berlin Wall. They literally made “industrial” music with drills, sanders and junk metal. Kalte Sterne compiles the band’s early singles from 1980-82; it documents their birth as urban primitives banging away tribal rhythms with leader Blixa Bargeld throwing tantrums and whip-cracking his guitar like a sweatshop foreman. “Aufrecht Gehen” stands out for its haphazard locked groove, while “Pygmaeen” offsets samples of triumphant orchestras with barbarians attacking the opera house. Kalte Sterne is more vital than the work of the “industrial rock” scabs who later bankrupted the factory.
