The first song is by Mari Boine, a Norwegian Sami musician who puts a modern spin on the Yoiks of her native Sami people who live in the Northern parts of Norway, Sweden, Finland and Russia. Yoiks are a traditional form of song in Sami music.
The second song is Tuvan Internationale by Huun Huur Tu who are throat singers from the Republic of Tuva which is located in the geographic center of Asia.
The third song is by a band from McMinnville Oregon, where I used to live, called Insofar.
Coincidentally I just got back from a Murder By Death concert in McMinnville Tennessee which was 333 feet below the earth's surface in the Cumberland Caverns.
