This Understage concert brings together two solo performances: one by German producer Thomas Brinkmann, a major figure in international electronic music, and the other by Portuguese percussionist and sound artist Vicente Mateus, in an evening dedicated to sonic experimentation and contemporary languages spanning electronics, percussion and immersive listening. Through this double bill format, Matéria Prima seeks to establish dialogues between local contexts and international circuits, bringing emerging artists into proximity with key figures in contemporary experimental and electronic music.
