This video and more importantly the audio was created by Tim Opie using the composition technique eco-structuralism.

Eco-structuralism is a technique for composition in which sound recordings, particularly field recordings, are analysed for underlying structures and patterns, whereby the analysis results, used in conjunction with a strict set of rules, become the constructs of the musical work.

The field recordings for this composition were recorded at a waterfall near The Basin in Victoria, Australia. It was recorded just after the first rainfall since the major fires on Black Saturday began, which had been burning for the last two weeks. There was some ash in the air. There was very little water in the river, just enough to get some flow, and a little fire relief.
