The Calmfort video art was created as part of the two-week expedition "To Understand Vladivostok: a fort city, a resort city" Based on the textures of the Pospelov Fort. The visual part is the documentation of the fort, and the audio track is the result of its sonification: with the help of a special program, the artists transformed photographs of the walls, rooms and details of the fort into sound samples. The resulting musical composition in the dark-ambient style combines states of calm, doom, anxiety and confusion – these are the feelings that the authors left after visiting this place.
