Warfare Noise is considered one of the most important documents in the history of South American extreme Metal. Never before available outside of Brazil, and long out of print, Warfare Noise represents the first official appearance for classic Cogumelo Records bands Holocausto, Chakal, Mutilator and Sarcofago. An absolutely essential release for those into bands such as Bathory, Blasphemy, Vulcano and early Sepultura.
