Two reference figures in the universe of experimental and improvised music finally come together in a duet after their paths crossed in other contexts of artistic projects. Yaw Tembe, trumpeter, composer, visual artist and curator, develops work characterized by the exploratory study of fragility and ephemerality in a process that crosses the various areas in which it is articulated. Joana Guerra, composer, cellist and singer, whose passion for experimentation has led her to regular collaborations with numerous musicians, dance and theater projects, influencing a unique universe in permanent expansion. The intersection of Yaw Tembe’s trumpet and electronics with Joana Guerra’s cello and singing evokes an exercise in futuristic archeology and is structured around the concept of memory, not as a nostalgic reading. In this research into the imperfect temporal continuum, the musicians are inspired by the sandy matter and the ancestry that is contained in a stone, by the fossils that contain the past and the future in a moving horizon. On these lines of research and thought, Joana Guerra & Yaw Tembe inscribe their unique sound aesthetics.
