Colectivo Casa Amarela occupies O Espaço do Tempo through its curatorial project Jejum, bringing together Aires, Carga Aérea, and alga — musicians accustomed to individual creation — accompanied by Mafalda Melim on video, for a week of sound exploration that pushes boundaries. Each session navigates all possible combinations, solos, duos, and trios, transforming the space into a ritualistic laboratory of improvisation, where sounds collide, merge, and reinvent themselves. The video adds an enchanting, experimental dimension, expanding the perception of sound and presence. The encounters culminate in open performances for the community: long journeys where the unexpected reigns, improvisation is absolute, and each moment is unique, irreproducible, and truly unheard-of.
