This is an international conference sponsored by the International Computer Music Association(ICMA). Research presentations on the theory and technology of computer music and the latest computer music works will be presented. My work “this is like ..." (a video work using three displays and a projector) will be selected for the 2020 concert program. However, it was performed in July 2021 due to the postponement due to the coronavirus in the previous year. This year's sponsorship is Pontificia Universidad Católica de Chile, Santiago, Chile.
