The abandoned railway section Castellaneta - Gioia del Colle in Puglia represents one of those places that meet the definition of 'undecided spaces', heterogeneous and dispersed realities which, precisely because of their nature of uncontrolled spaces, constitute a refuge for diversity, a product of the rational organization of the territory. A 'subnature' that lies between the natural world and the artificiality of industrial and urbanization processes. A six-hour walk in which Polisonum traveled an abandoned railway section, extending the vegetal dynamism of the Third Landscape theorized by Gilles Clément to the field of sound. An audio-video survey without interruptions, a sensitive accumulation of data on space, a continuous flow of heterogeneous stimuli. Presented at ArtVerona - Verona Contemporary Art Fair, 2017, '778FS' is an audiovisual work in which the memory of the journey is transformed into a random succession of connections between image and sound, revealing the fragmentation and indeterminacy of the places crossed. This release comprises a selection of about 20 minutes taken from that "six-hour walk." Same tracks on both sides (total: 40 min.). Edition of 125 copies, of which 100 for sale. Written by, composed by, performed by Polisonum (Filippo Lilli ~ Donato Loforese). Mastered by Giuseppe Ielasi.
