Killer Jack

**Killer Jack** is a Brazilian punk rock band known for their raw energy, socially charged lyrics, and DIY ethos. Formed in São Paulo in the early 2000s, the group has carved out a loyal following in Brazil’s underground music scene with their blend of fast-paced riffs, anthemic choruses, and themes tackling inequality, urban struggles, and political disillusionment. Tracks like *Funcionário do Mês* and *O Mundo É dos Órfãos* showcase their knack for pairing gritty storytelling with head-banging rhythms, while recent releases like *Aceita Que Dói Menos* and *Vou Seguir* reflect their enduring relevance in Brazil’s counterculture.

Though not widely mainstream, Killer Jack’s music resonates with fans who crave authenticity and rebellion. Their live shows are legendary for their intensity, often turning small venues into sweaty, cathartic gatherings. With a discography that refuses to shy away from life’s messiness—like the frustration in *Até Quando?* or the existential shrug of *Não Sei*—they’ve cemented their status as unapologetic voices for the overlooked.
