Sepultura are one of the worst cases of the whole good-to-bad band scenerio that has been plaguing metal for years. How a band goes from the death metal onslaught Bestial Devastation to the wiggerfied groove "metal" monstrosity Chaos A.D. is beyond me. I just pretend they broke up right after the release of that album.
Anyway, this is Sepultura from their best days (the Bestial Devastation and Morbid Visisions era). It's got surprisingly good sound quality considering it was probobly recorded on a boombox. It even has a cover of Slayer's epic song "Black Magic" from their 1983 debut masterpiece, Show No Mercy. Enjoy.
