Who’s There? is a haunting and immersive exploration of fear, based on the personal experiences of composer Celia Swart. The piece began as a recurring nightmare during her youth, where she would be alone in her house, terrified by the unknown presence behind a door. The fear of something trying to break in would provoke a desperate struggle with the door, but the source of the danger was never revealed. This cycle of confusion and dread became a central theme in Swart's composition.Through XTRO Percussion—featuring performers Antonio Bove, Gabriele Segantini, and Miguel Varela—the nightmare is channeled into music, with the breathing of the performer (Varela) serving as a reaction to the fear. The piece portrays the journey through various stages of anxiety and tension, ultimately leading to a moment of surrender, where the door is opened and the unknown is finally faced. This composition turns the artist's personal fear into a sonic experience, giving form and expression to what was once inescapable.Composition and Artistic Direction: Celia SwartD.O.P, Lighting, Edit, and Colour Grading: VidamirPerformers: XTRO Percussion (Miguel Varela, Gabriele Segantini, Antonio Bove)Breathing and Artistic Mix: Celia SwartSound Recording and Mastering: Luuk van LeeuwenDoor Frame Construction: Rob van den Broek/QEMActing Coach: Yolanda de GreeuwSpecial Thanks: Eli Dorsman, Arjen Bijtelaer, Pink, Vincent van den Ouden, Jos Eilert, Esther Gottschalk, Dutch Composers Now, Prins Bernhard Culture Fund, Buma Cultuur, Social Buma
