1. Industrial Music is difficult to define but it has to do with experimentation, improvisation, and pure noise. Is about programing hard noisy sounds on samplers, scratching the guitar strings by adding distortion and phaser, hitting hard on metallic devices, and screaming or talk loud on a voice machine.
2. Industrial Music is not just music is a movement that confronts pop culture, commercialism, or anything that is mainstream. Music that is not sold in the market or they don't play it on the radio. It was made noisy for a purpouse so it would not attract popular kids, like jocks, preppies, or posers. Bands like Nine Inch Nails, Ministry, KMFDM, or either Marilyn Manson are NOT Industrial because they are part of the market and they are already mainstream. Industrial Music is EXTREMELY UNDERGROUND.
3. Industrial Music doesn't have any lyrics is mostly instrumental but they are some bands that predict messages on their improvasations or they just say strange stories.
