Industrial music is a form of experimental music which emerged in the 1970s. In the 1980s, industrial splintered into a range of offshoots, sometimes collectively named post-industrial music. This list details some of these offshoots, including fusions with other experimental and electronic music genres as well as rock, folk, heavy metal and hip hop. Industrial genres have spread worldwide and are particularly well represented in North America, Europe, and Japan. Industrial music Industrial music comprises many styles of experimental music, including many forms of electronic music. The term was coined in the mid-1970s for Industrial Records artists. The first industrial artists experimented with noise and controversial topics. Their production was not limited to music, but included mail art, performance art, installation pieces and other art forms. Prominent industrial musicians include Throbbing Gristle, Cabaret Voltaire, Boyd Rice, SPK, and Z'EV. Test Dept, Clock DVA, Nocturnal Emissions, Laibach, and The Leather Nun subsequently participated in the movement. German group Einstürzende Neubauten forged their own style, which mixed metal percussion, guitars and unconventional instruments (such as jackhammers and bones) in stage performances that often damaged the venues in which they played. Post-industrial developments Dark ambient Dark ambient projects like Coil, Lilith, Nurse with Wound, Lustmord, and Zoviet France, evolved out of industrial music during the 1980s. These artists make use of non-musical material and noise, but less abrasively than other post-industrial musicians, bordering more on ambient music. The last material that Throbbing Gristle recorded in the studio, In the Shadow of the Sun and Journey Through a Body, was ambient, and pointed in the direction that TG's offshoots (notably Coil, Chris & Cosey) would take. Other artists include Long Distance Poison, Hafler Trio, MRT, Kim Cascone, Controlled Bleeding, Nine Inch Nails (on their album Ghosts I-IV), early Techno Animal, prominent game music composer Akira Yamaoka, Robin Rimbaud, Final and Deutsch Nepal. Electro-industrial Electro-Industrial draws on Electronic Body Music (EBM), and developed in the mid-1980s. While EBM has a minimal structure and clean production, electro-industrial has a deep, complex and layered sound. The style was pioneered by Skinny Puppy, Front Line Assembly, and Wumpscut. In the mid-'90s, the style spawned the dark electro and aggrotech offshoots. Other artists include Haujobb, Lab Report, and Leæther Strip. EBM EBM combines elements of European industrial, German electronic music such as that of Klaus Schulze, music of the Neue Deutsche Welle electropunk scene. It first came to prominence
