Sistemas Inestables is an enigmatic and emergent post-rock musical ensemble hailing from Chile, known for their ethereal soundscapes and evocative instrumental compositions that resonate with depth and introspection. The band's journey began with a dedicated vision to explore the boundaries of instrumental music, leading them to craft tracks that combine atmospheric textures with intricate rhythms and haunting melodies. Their music often takes listeners on an expansive sonic experience, moving seamlessly between moments of delicate ambiance and powerful, crescendo-driven climaxes.

With their breakthrough album "O," originally released in 2018, Sistemas Inestables caught the attention of the post-rock community both locally and internationally, earning them a spot at the prestigious Dunk! Festival in 2019, where their live performance was recorded and subsequently released as "O (Live at Dunk! Fest 2019)." Demonstrating their versatility and commitment to innovation, the band also released "O (Reworks)," breathing new life into their original compositions through reinterpretation and remixing techniques. Alongside these reinterpretations, singles like "Motus" and "Oppidum," as well as a remix of their own track "Retorno de Saturno," showcase the band's evolving sound and their continuous pursuit of emotional and musical exploration, solidifying Sistemas Inestables' place in the avant-garde of the post-rock genre.
