Avian Humanoids is a supernatural sound walk around five trees near the Nieuwe Kerk in The Hague, where mythical bird‑people come to life. Inspired by figures from global folklore, such as Gamayun and Harpies, you’re guided through soundscapes featuring voice‑altered compositions and immersive Dolby Atmos audio. Each tree reveals a unique musical encounter between human and bird‑human, blending classical music, electronics, and opera. Through your phone and the SonicMaps website, you experience an alternative reality filled with wisdom, mysticism, and poetry during a walk of about 30 minutes.
