Towards the end of this time, formed the band, but only now created the most critical and most obnoxious songs that would have been inconceivable before 1985 (I heard believe I have that Max Cavalera was even briefly arrested and interrogated by the regime because of his artistic doings as a felons). Best thrash metal with tribal influences, to (socio-) political or psychological personal texts - - From a musical point of view of their own distinctive style begins to emerge here, which on "Roots" is a step deepened intense. The opener, Refuse / Resist 'presents for me, as for many others, one of the best songs of Sepultura altogether, and maybe even the superlative par. A masterpiece that Cavaleras expresses four elements (heart, Faust, soul, mind), these themes together. But this applies to most of the songs, among which one, Territory ',' Amen ', and, Clenched Fist' should highlight as consistently deep and straighte Thrash numbers.
