On a Singing Duet for a New Month and Monday

In throat singing, also called overtone singing, overtone chanting, or harmonic singing, the singer produces a melody of various notes by manipulating the air as it moves over the vocal cords and through the mouth. Although most associated with the Tuva region of Siberia, cultures in Altai Republic, Khakassia, Chukchi, Mongolia, Tibet, Kazakhstan and the Uzbekistan, northern Canada, northern Europe, and South Africa also have throat-singers.

I do not believe the person in this video is from any of the cultures listed above, but I have to give him credit for doing a duet with himself. A new hobby for Little Beeze?
