Industrial is a genre of experimental music formed in the early to mid 1970s. Although it was never precisely defined, some of its characteristics included the use of non-musical sound, electronic noise and tape manipulations which were used to create anything from industrial rhythms to abstract noise or dark atmospheres. This style was pioneered by Throbbing Gristle, SPK, Cabaret Voltaire, and other bands somehow involved with the label Industrial Records from the UK. They often made use of self-made electronic devices, synthesizers, improvised instruments, sound collage/cut-ups and various sound effects.
During the 80s many of the early industrial groups steered into a more accessible (even commercial) direction, but the techniques, sound and aesthetics laid the base and influenced the later formation of Noise, Power Electronics and even Dark Ambient.
