Berne Krause has been recording the natural world for decades. His book “The Great Animal Orchestra” is one of the most important things you can read — both for insight into the ways we humans evolved as a species in a world saturated with music, and for (mostly very depressing) insights into just how badly we’ve fucked things up in the short time that we’ve been acting with institutionalized intelligence.
Here’s a link to his website (strongly recommended).
Check out his Audio Archive:
The Wild Sanctuary Audio Archive represents a vast and important collection of whole-habitat field recordings and precise metadata dating from the late 1960s. This unique bioacoustic resource contains marine and terrestrial soundscapes representing the voices of living organisms from larvae to large mammals and the numerous tropical, temperate and Arctic biomes from which they come. The catalog currently contains over 4,500 hours of wild soundscapes and in excess of 15,000 identified life forms.
Fully half of the natural soundscapes in this rare set are from habitats that no longer exist, are radically altered because of human endeavor, or have gone altogether silent.
His TED talk sums things up nicely.
