The Laotian Khene or Khaen

It's like one person playing the entire reed section of an orchestra. It's also inscribed on the UNESCO Intangible Cultural Heritage list.

The Khaen is a free reed mouth organ of the Lao people (Lowland Laos & Northeastern Thailand) and is a symbol of Lao cultural identity. The khaen is made of 6–18 bamboo pipes put in two rows, which are mounted on a windchest. Each individual bamboo pipe has a free reed and a finger hole, once the finger hole is covered by the player the pipe can produce a pitch. The khaen is polyphonic, meaning it can play multiple sounds at once, and typically has one or more drones.
