Polisonum (Filippo Lilli, Donato Loforese) is an artistic collective using sound as a method and device of investigation to explore processes and metamorphoses linked to the present time. It is characterized by a research-based approach directed at listening to and interpreting the spaces in which it operates through sound installations and performative acts in strong dialogue with visual languages. Thanks to its hybrid identity, Polisonum realizes projects that feed on a practice of study and analysis in relation to other fields of knowledge. Polisonum's work has been shown in several institutions and festivals, among others: Una boccata d'arte (AV), Fondazione Volume (RM), Kunst Halle Sankt Gallen (CH), Palazzo Altemps (RM), Palazzo Pallavicini (BO), Romaeuropa Festival (RM), OTO Sound Museum Zurich (CH), The Others (TO). The collective collaborates with La Sapienza University of Rome Faculty of Civil and Industrial Engineering on the Green Network project for the Public Space Biennial. In 2018 Polisonum received the Special "Utopia" Award of the Talent Prize and in 2016 the Best Unpublished Work Award during The Others. Over time the collective has released several vinyls, among the latest Passi 13'36'' in collaboration with the artist Alfredo Pirri.
