Finnbogi Pétursson has from the outset combined sound and visual presentation in installations that cross the boundaries into music, performance, and uncharted territories where he extends the possibilities of technology. He transforms sound waves into light, reflected off pools of water, and creates mobile sculptures that use feedback to produce an endlessly renewing auditory environment. His pieces range from the scale of architecture to minute, almost ethereal, sound-producing objects, and he has also released recordings of compositions, often collaborating with musicians and composers.
