Nekrokult channels the unholy trinity of early Bathory, Celtic Frost, and Sarcófago into punishing black/thrash metal with a heavy crust and d-beat undercurrent.

Their debut Victim of Yourself (2013) announced a relentless, Teutonic-influenced thrash attack, and the band sustained momentum through Agony (2016) and Downfall of Mankind (2018) despite numerous lineup changes. Amaral has helmed the project through multiple roster shifts, continuing into the Napalm Records era with Perpetual Chaos (2021) and Jailbreak (2023).

This Belém trio — Rodrigo Barros on guitar and vocals, Cosme dos Santos on bass, and Paulo Wallace on drums — deal in fast, working-class crossover thrash with lyrics that swing between urban violence, horror film nods, and a frank affection for cachaça.
