One of the longer-running voices in the São Paulo hardcore and metalcore scene, Paura emerged in 1995 from members of No-Violence and Garage Fuzz, fusing the DIY ethics of hardcore with heavy metal weight and politically charged lyrics around vegan straight edge and anti-homophobia themes. Their output spans from the 2014 album "Tameless" through to "Karmic Punishment" (2023), maintaining a raw urgency across nearly three decades of activity.

Project46 grew out of a Slipknot tribute act called Kroach, with guitarists Jean Patton and Vinicius Castellari steering the band toward original metalcore. Their releases include the full-lengths "Doa a Quem Doer" (2011) and "Que Seja Feita a Nossa Vontade" (2014), and the bilingual album "TR3S" (2017), which earned them spots at major rock and metal festivals across South America.

Prometherion grew from guitarist Vinícius Starteri's earlier project Alkimistal, fusing Swedish melodic death metal, New York hardcore, and Bay Area thrash into a sound the band calls modern death metal. The name is a neology blending Prometheus and Therion, reflecting a lyrical focus on how people endure hardship, and the band has maintained activity through SoundCloud and streaming platforms despite internal lineup turbulence.
