Ratos de Porão (Portuguese for "Basement Rats") formed in São Paulo in November 1981 and went on to release Crucificados pelo Sistema in 1984, the first hardcore punk LP issued by a Latin American band. Vocalist João Gordo joined for that debut and has remained the band's frontman ever since; their 1987 album Cada dia mais sujo e agressivo is widely credited as the first Brazilian crossover thrash record of note, and the band has since released more than fourteen studio albums while continuing to tour South America, North America, Europe, and Asia.

Realidade Encoberta is a crossover thrash band from Recife, Pernambuco, originally founded in 1987 by Nado and Daniel Malcriado; the band disbanded after Nado's death and reconstituted in 2013 with a new lineup anchored by vocalist Carlos Underground and guitarist Túlio Falcão. Since the reunion they have released Momentos Antes do Caos (2014), Morte e Progresso (2016), and Não Vivamos Mais Como Escravos (2019), the last of which closes with a Minor Threat cover.
