Looking for a recording!

Hi! I'm a Pole and recently I've seen this video on the UNESCO Youtube channel;

The song starting at 1:49 struck me with its singular beauty and I can't stop thinking about it but I can't find it. The fact that I don't know anyone who speaks Georgian doesn't help. Does anyone happen to know the song or the recording? What's it about? Thanks in advance!
