No surprises here really. Sepultura was one of my first favorite metal bands that was on the more extreme side. Of course I got into them around the time that Chaos A.D. was released. Still, Sepultura put out one hell of a good groove metal album with that release. Even Roots has its moments, mostly due to the use of tribal percussion. However, their best material is undoubtedly their earlier stuff. Morbid Visions and Bestial Devastation are excellent examples of early black/death metal and Beneath the Remains is one of my all-time favorite thrash metal albums. After vocalist Max Cavalera left, Sepultura became more of a hardcore/groove metal band and I kind of lost interest. Of course Max's stuff was not much better. Still though, the material from their debut EP through Chaos A.D. is ridiculously powerful.
NOTABLE SCENES: Brazil had an amazing scene in the mid 1980's that blurred the lines between thrash, death, and black metal.
