A genre of music started by such bands as throbbing gristle. It is characterized by it's brutal and harsh sounding music wiht lyrics usually associated with pain and .. stuff like that. It's like goth but heavier. Many 'true' industrial fans like to call bands such as nine inch nains fakes. I do agree with the idea that nine inch nails is NOT an industrial band; but get mad at the dumb-ass fanboys who make it look like they're pretending to be industrial and not the actual band.
Wow, listening to industrial music is like a robot having sex with your head. In a good way.
