Why weird? A music with the technical demands of classical music, channeling the angst and rebellion into unity. A music with power - the brotherhood adversarial nature of the mosh is something to be experienced - everybody is doing their best to crush all of your bones, except when you stumble or fall - then literally 20 hands will pick your up and throw you away to safety. A music that is good for training, fragging people in Quake, sex or invading neighboring country. A music with infinite variability and versatility. Why is weird that it transcends borders, cultures and generations?
