Industrial music started off as an offshoot of punk rock when British bands like Cabaret Voltaire and Throbbing Gristle started experimenting with electronics and imitated the mechanical sounds of England's urban landscape. Some early bands like Germany's Einstürzende Neubauten took the industrial aesthetic to its extreme, using power tools as instruments and metal oilcans as drums. During the late 1980s, industrial bands like Skinny Puppy, Front 242 and Ministry began to adopt the synthesizers of new wave and the distorted guitars of heavy metal, with jackhammer-tempo drum machine rhythms providing the beat. Nine Inch Nails became immensely popular during the early 1990s by retaining the sounds and production techniques of industrial music but relying on more traditional song structures.
