Ratos de Porão, whose name translates as basement rats, is a Brazilian hardcore punk band formed in São Paulo in 1981. The group became one of the most influential punk acts in Brazil, moving from raw hardcore into faster crossover thrash while keeping an aggressive, politically charged sound. Short clips like this one circulate on soundboards and social media because the band's riffs are instantly recognisable to punk fans and give edits a raw, underground edge. The sound remains popular with creators who want a short burst of Brazilian punk attitude without using a full song.
