One of the earliest Brazilian thrash bands, Necromancia came together in São Bernardo do Campo in the mid-1980s and spent decades honing the groove-inflected thrash attack that defined their later records. Check Mate (2004), produced by Sepultura's Andreas Kisser, marked a high point in that evolution, blending the bone-dry riffing of Pantera-era groove metal with their São Paulo thrash roots, while Back from the Dead (2011) pushed the tempos back up toward their earliest material.

Negativus blends old-school death metal with groove-laden heaviness, drawing on the sounds of Obituary, Entombed, and Celtic Frost while writing all their lyrics in Portuguese. Their 2024 debut "Detestabilis" features vocalist Eduardo Jarry alongside guitarist Thyago Trajano, bassist/guitarist Victor Hugo Targino, and drummer Eduardo Amorim, delivering ten tracks of punishing, mid-paced brutality.

Num is a groove metal band from Buenos Aires, Argentina, whose sound blends thrash, djent, and alternative metal influences into a dense, rhythmically focused attack. The band released three albums in rapid succession — NUM (2014), Desarreglos (2015), and Lo Que Sangra (2017) — building a reputation in the Argentine underground metal scene.
