L'ENIGMA DELLA QUARTA CORDA E LA VIA LATTEA (THE ENIGMA OF THE FOURTH STRING AND THE MILKY WAY), a work by Nato Frascà (1931-2006) that evokes an electromagnetic scan of a Mediterranean landscape, will be exhibited in the rooms of the MAMeC in Penne. The installation is designed in a darkened room, with a projector that magnifies the work and some of its details, creating an immersive experience. After a minimum three-minute viewing/immersion, visitors can express themselves pictorially on large sheets of paper provided. The sound accompanying this experience is based on regenerative sound frequencies.
