Bad Resilience is a grindcore and noisecore project from São Paulo, Brazil, founded in mid-2024 by musician Rodrigo Chenta. The project fuses diminutive riffs with raw blast-beat grind, drawing lyrical themes from Christian theology — including kenosis, ordinances, and martyrdom — with lyrics in both English and Spanish. Their debut album Mutilated Head (2024) arrived alongside the single Stoning, establishing a deliberately brutal and theologically charged identity.

Their entirely wordless approach lets the genre-blurring density of the music speak for itself.
