At its core, the work is designed around the concept of suimin (sleep). In the context of Japanese audio dramas, this involves using binaural recording techniques—microphones shaped like human ears—to create a 360-degree soundstage. When a listener wears headphones, it creates the illusion that the performers are physically present.
