ruído/mm

Formed in Curitiba, Brazil, in 2003, ruído/mm (ruído por milímetro) has become a cornerstone of the Brazilian independent instrumental scene. Their sound identity is built on a foundation of post-rock but is heavily modified by elements of jazz-fusion, math-rock, and Brazilian regional rhythms.

Unlike many of their Western contemporaries who rely on 'wall of sound' crescendos, ruído/mm emphasizes intricate, interlocking guitar work and highly dynamic percussion. Their career arc shows a steady evolution from the raw, experimental textures of 'Série Cinza' to the refined, cinematic production of 'Rasura' and 'A É Concavo, B É Convexo'. Culturally, they represent a sophisticated wave of Brazilian art-rock that looks outward toward global genres while maintaining a local, gritty identity. They are frequently associated with the 'Sinewave' label collective and have influenced a generation of South American instrumental acts. Critical consensus highlights their ability to maintain tension without relying on genre clichés, praising their technical precision and atmospheric depth.
