It sounds like a bird’s song, and you can’t take your ears off it. But it’s not – it’s just the popping bubbles of a melting glacier. A group of musicians equipped with sensitive microphones and headphones set out on an exploration. They head to places in the Czech and Icelandic countryside both marred by industry and untouched by man to discover and understand the sound of catastrophe – the sound of ongoing climate change, which in itself can be far more beautiful, and more imaginative, than what it heralds. While sight allows phenomena and things to be encompassed in a static state and in a certain entirety, hearing allows us to understand how they affect and clash with their surroundings. Sound is the consequence of an event that happened in the past and points towards a future now being decided, one that may potentially be inevitable and destructive for us. It cannot yet be seen in the invisible landscapes, but – if we listen carefully – it is already there.
