Brazilian thrash metal legends Sepultura helped put South American metal on the global map with landmark albums like 'Beneath the Remains' and 'Arise' before radically reinventing themselves with 1996's tribal-metal masterpiece 'Roots,' which fused extreme metal with indigenous Brazilian percussion and world music.

Their influence on the global metal scene, particularly in bridging extreme metal with indigenous and world music traditions, is immeasurable.
