Extremely minimal drone. Whereas other similar drone albums rely mainly on manipulation of the pads themselves for the texture of the pieces, this takes a more interesting approach by incorporating nature recordings instead. The drones are still textured of course, just not nearly as much as other acclaimed releases because they don't need to be. The nature recordings give the soundscapes all the texture you would want out of a release like this; they give the music a really serene atmosphere, and make it unbelievably relaxing.
It's hypnotic and soothing enough to force you to sleep whether you want to or not. If melatonin isn't working, this might.
