Zangbeto is the traditional voodoo guardians of the night in the Ogu or Egun religion of Benin, Togo, and Nigeria which are known as the “Nightwatchmen”. Similar to Egunguns, they are highly revered and act as an unofficial police force patrolling the streets, watching over people and tracking down criminals and presenting them to the community to punish. Edit: I just listened to a vuvuzela and oh god it sounds like a fucking swarm of bees when a crowd of people was using them at once. And I listened to a didjeridoo again and if I heard those combined I think I would have nightmares.
Besides, I don’t have Aboriginal heritage, so it’s not really my place to tell you what is and isn’t okay. I can only tell you that they’re an important part of another culture with rather stringent rules attached and whatever you decide to do with that information is up to you really. I’ve seen this in southern Senegal (a shared culture with the Gambia). These dancers love to terrify kids, who run away screaming and then edge back slowly to keep watching, only to get chased again, and again. They never actually catch any of the kids though.
