Sound has always been associated to divination practices. In a time when the imagination is rendered short by a prevalent fixation on dystopian futures, we tune into the resistant voices that create an outside to this totalized world by nurturing structures of individual and communal resistance. *Sonic Utopias* is a sonic fiction series of utopian narratives and tales of subversion from a (not so) distant earth. Five seashells contain another narrative about the future, while the sand refers to the childlike practice of building sandcastles; a metaphor for the necessity of world-building in frail times. Sonic Utopias is a collaborative series of sonic fiction hosted by Movement Radio - Onassis Stegi (ATH, GR) in 2021.
