Night woodland. Sonorous owls. Soft nocturnal breezes catching high in the broad-leafed trees. A panoramic woodland in spatial sound, collected by the Lento box alone.

Always so fascinating to us is how the natural world sounds at night, when there's absolutely nobody about. It's quite difficult to record though in its true resting state because human made noise is audible even from distances of ten miles or more. But here on a calm May night in Big Wood on the Leicestershire-Rutland border the Lento box found it. A forest at rest. Owls calling across wide reverberant spaces. Undulating wind moving high in the trees. And so many aural shadows. Velvet brown, shapeless, and yet there.

Listening to this collected soundscape in spatial audio makes us think, how owls don't sound like they look. Their aural presence is not stark or silvery at all. Their calls are sonorous and have a timbre more like short wooden flutes, blown and tongued with such precision. They sound more golden than silver. The kind of golden green light you sometimes see when a shaft of moonlight filters down through broad leafed trees.

* The Lento box collected this soundscape in May tied to a tree in Big Wood on the Leicestershire- Rutland border. This location is remote (as far as we can get in the UK) and the sound landscape is predominantly natural, though some distant echoes of human made noise are sometimes heard filtering through the forest. We're sharing this segment as *sleep safe* but some people may not feel it is because of the owl calls. This segment begins about an hour after sunset. Sheep and lambs are audible, and some periods of distant squeaking probably from small mammals living in a nearby tree or in a nest at the foot of the tree.
