The International Institute for Critical Studies in Improvisation (IICSI), in partnership with the Guelph Jazz Festival and the University of Guelph, invites proposals for presentations at our annual interdisciplinary international conference. The colloquium will take place September 11-13, 2024, as part of the 31st annual Guelph Jazz Festival. Featuring panel discussions, debates, performances, workshops, keynote presentations, and critical conversations among researchers, artists, and audiences, the colloquium fosters a spirit of collaborative, boundary-defying inquiry and dialogue, and an international exchange of cultural forms and knowledges.
