Allegedly, Jim Wilson took a recording of crickets, slowed it down 1000x and layered it on top of the same sounds at original speed. The result is haunting and beautiful.
[Jim] Wilson, he’s always playing with time. I heard a recording recently of crickets slowed way down. It sounds like a choir, it sounds like angel music. Something sparkling, celestial with full harmony and bass parts – you wouldn’t believe it. It’s like a sweeping chorus of heaven, and it’s just slowed down, they didn’t manipulate the tape at all. So I think when Wilson slows people down, it gives you a chance to watch them moving through space. And there’s something to be said for slowing down the world.
