The record, bearing a track recorded on the edge, is deformed by swelling. The stylus is forced to ride in the groove, going up and down. The title of the work is taken from the Inferno’s third Canto, where Charon takes the damned souls to the opposite shore of the Acheron River, which Dante defines with the synecdoche “umber’d wave” (the “onda bruna” of the title, in Italian). Charon as a smuggler, a tragic vision of the current situation in the Mediterranean, addresses the audience with a question: what is the link between migration phenomena and climate inequality?
