Tommi Grönlund and Petteri Nisunen, Ultrasound Installation, 1996 © Petteri Nisunen
Sonic installation at Kunsthal Rotterdam
This large ultrasound installation by the Finnish artist duo Tommi Grönlund and Petteri Nisunen was shown for the first time at Manifesta in the recently opened Rotterdam Kunsthal, designed by Rem Koolhaas. In this work, characterised by high frequency tones which came together between two parabolic reflectors, a powerful sonic environment was generated in order to immerse the visitor in both light waves and sound waves that are otherwise imperceptible.
