After this post, my ADD got the better of me and I went looking for interesting vocal music. Below are some videos I found beginning with the most unusual.
From the Inuit
From Mongolia, overtone singing with accompaniment
From Georgia-the Country, not the state, though it has a state and used to be part of a monolithic one!
Istanbul is Constantinople again
From Germany. This’ll lighten the mood!
From Scotland-Interesting note, gaelic was spoken in parts of the Carolinas and Georgia in the 17th and 18th centuries.
One more from Scotland. This one is Puirt a Beul with a distinctly American setting except for the uilleann pipe solo.
