Salford Sonic Fusion Festival celebrates cutting-edge international explorations in contemporary music from across the globe and blurs the boundaries between avant-garde classical, experimental electronic popular and improvised music. Events on 3-4 April included acousmatic and audiovisual works by MANTIS composers using a 48-loudspeaker sound system a one of the largest HD screens in Europe. I was happy to present the “Apollonian Gasket“, a piece exploring the kinematics of a custom 3D virtual instrument inspired on this mathematical fractal object.
