About this time last year I was out in the wilderness making music. While I was there, I recorded some of the natural sounds in that environment. It was always noisiest around dawn and dusk. At first it was a bit unnerving because it was so loud, eerie and yet ubiquitous. You couldn’t pinpoint the source. It just seemed to come from everywhere. After a few days I hardly noticed anymore. Check it out. Try it with headphones.
