Batzorig Vaanchig is a Mongolian throat singer. Here he collaborates with his daughter Marla. The song is "Xotgoidiin Unaga" (foal from Xotgoidiin), about a horse with a white blaze who always wins races. One commenter summed up the performance:
When she began singing, I smiled, when he began...I became one with the universe.
He is a talented musician, and she is following in his footsteps, but together they are just adorably wholesome. Read more about throat singing here. -via reddit
