This Czech version of the Hans Christian Anderson Little Mermaid fairytale is the most dreamlike realisation of an underwater world you will ever see on the screen. The Zdenek Liska soundtrack is haunting, mixing orchestral and electronic elements that resonate with the intensity of the sea. There are deep electronic oscillations in here that feel like living organisms, and tightly filtered tuned white noise is used to dramatic effect. Composer Liska also used on set recordings effected and manipulated to add yet another layer of unreality.

The film itself is currently unavailable to buy. The full soundtrack can be purchased from obscure soundtrack hunters Finders Keepers, whose Doug Shipton I have to thank for introducing me to this masterpiece of European cinema.
