Organized as part of the European REACH project, the Improtech international workshop-festival combines the universal art of improvisation with digital intelligence and AI culture through a series of conferences, interdisciplinary workshops, installations, performances, and concerts. After traveling across three continents and bringing together leading artists and science figures in the field, Improtech returned to Ircam, its alma mater, in December 2025, for an extraordinary edition focusing on the relation between improvisation, composition and spatiality, with a special tribute to the great composer and Music AI Pioneer George Lewis.
