Noise music can be an incredibly broad genre, incorporating any kind of music that harbours some sort of noise. Here it is only used as the so-called "Noise Music Scene" which is a separate school of Industrial music emerging in the early 80s. At this point, the Industrial scene was taking a more Dance-orientated approach, with both EBM and Electro-Industrial emerging as either more repetitive or melodic evolutions. The opposite direction – strictly noise, by any means possible – brought forth a Post-Industrial wave of Noise-related subgenres lasting until today. The number of subgenres, barely discernable for the untrained listener, is stupefying – Power Electronics, Power Noise, Japanoise and more. Japanoise started as a vague umbrella term for anything noise-related from Japan but gradually formed into a defined genre with its own subculture. Noisecore employs extremely sharp and harsh sounds, instead of the deeper and the more subtle tones of other Industrial. It is this quest for music as a nemesis of the mainstream, that gives testimony to the saturation of possible music genres.
