This modern work by Caldini utilizes complex, minimalist-inspired textures that create a dual-layered sonic field. It is unique for its meditative pacing and the precise control required for its repetitive patterns.
The main technical challenge is managing the subtle layering of voices while maintaining a strict, unchanging tempo.
