Georgian Polyphonic Singing

Polyphonic singing is not unique to Georgia; however, Georgian polyphony emerged "independently," resulting in a unique acoustic framework. In fact, it is recognized by UNESCO as an Intangible Cultural Heritage of Humanity, and is particularly ancient (pre-Christian). I will not claim to know what exactly is going on here. Instead, I recommend you lie down in the grass, surrender to the earth, and fill your ears with microtonal madness.
