IMPROTECH CONCERT #1at Espace de Projection, Ircam
Psappho is the third instance of the project Xenakis Reloaded, after Evryiali (2022) and AI-Komboï (2023), paying homage to Xenakis through the choice of a well known piece and an improvised extension using AI. As the continuation of a broader research and performance project developed by Lorenzo Colombo and Marco Fiorini, two artists and researchers dedicated to exploring the creative potentials at the intersection of human and artificial intelligence in music, this new chapter will use Psappha (1975) as its central material. The project will investigate new modes of cyber-human co-creativity by integrating Somax2 and gestural control into an immersive spatialized performance environment. Psappha will serve as the compositional and performative ground, with a focus on gestural and temporal density, rhythmic articulation, and structural complexity, core features of Xenakis’s language, and fertile terrain for this novel interaction.
Organized as part of the European REACH project, the Improtech international workshop-festival is dedicated to combining the universal art of improvisation with digital intelligence cultures through a series of conferences, interdisciplinary workshops, installations, performances, and concerts. After traveling across three continents and bringing together leading figures in the field, Improtech returns to Ircam, one of its founders, for an edition that will focus on space and composition/improvisation and pay tribute to American composer George Lewis, an essential reference in musical AI.
This year, Ircam will host Improtech concerts in its unique concert hall, Espace de projection, encouraging a triple synthesis: that of acoustic instrumental culture with the original interactive artificial intelligence developed by the REACH project, that of solo improvisation with writing for mixed ensembles, and finally that of spatialization and sound immersion, also renewed by creative AI. This groundbreaking combination, supported by leading artistic figures in composition, improvisation, performance, and technology, will undoubtedly create a dazzling version of this sixth Improtech.
