(Spooky) Full Moons, Lunar Eclpises, Halloweens and... Devil's Moon. Soooo many different names for that one single moon, it's quite funny, to be honest :) Am not too much familiar with where things come from. But I do know in a hippie artsy village just outside my city of Amsterdam, they always celebrate full moon. I suppose this is also a heathens/pagans tradition since I think this is what the history is of what has become the experience of 'Ruigoord' (https://ruigoord.nl/)... that's the hippie village I was referencing.
Beautiful singing by the way! Short but powerful!
