**300 copies** The sound art of Jacob Kirkegaard explores ways to reflect on immediate complex, unnoticed or unapproachable aspects of the human condition or civilisation. His works have treated themes such as radioactivity in Chernobyl and Fukushima, melting ice in the Arctic, border walls in Palestine, and tones - otoacoustic emissions - generated from the actual human ear. Currently Kirkegaard works on two projects, one on the sound of global waste and waste management, and the other on sound environments related to the immediate human post mortem. With his peculiar alchemist approach and extensive research, complex phenomena and current conditions are portrayed through composition, installation, video and photography. Rather than providing answers, his portrayals create spaces for reflection. On Phonurgia Metallis he used three freely hanging metal plates - made of Iron, Copper and  Brass - each measuring 100x100x0.1cm. Piezo sensors and contact speakers were attached on the rear side of each plate, amplifying and mirroring their subtle and naturally occurring vibrations, evoking the characteristic resonant frequencies of each type of metal.

"For all the scientific rigour to Kirkegaard's research into the sonic possibilities of various materials, his work reveals an underlying fascination for the mysteries and myths embedded in them. His work channels an access to an inner world." A.H. Neset - The Wire
