Free Online HD YesMovies. Drawing from testimonies, recordings and forensic analysis, 450XL: A silent movie explores the politics of listening and the role of sound as both evidence and weapon. Using image, text and sound drawn from Earshot's 'earwitness' investigation of a reported sonic attack during a silent vigil in Belgrade in March 2025, the work investigates this contested event, and examines how acts of listening can reveal, reconstruct and challenge official accounts.
