A two day conference on sonic and audio-visual arts at The University of Greenwich, London. Professor Jeremy Welsh will be participating in the conference, presenting two recent collaborative projects: The Atmospherics, with sound artist Trond Lossius, and Accumulator, with Michael Francis Duch from the music dept. at NTNU. The Atmospherics is an ongoing series of audio-visual installations that have been exhibited in Norway and internationally since 2014, the most recent being The Atmospherics #9 at TEKS, Trondheim in August-September 2019. Accumulator is a concert work combining live performance for double bass with pre-recorded sound and video projection. The fourth version of the project will be performed at Belgin/Bergen Assembly and at the Sound / Image conference.
