The khaen (/ˈkɛn/; spelled “Khaen”, “Kaen”, “Kehn”[1] or “Ken” in English;[2] Lao: ແຄນ, pronounced [kʰɛ́ːn]; Thai: แคน, RTGS: khaen, pronounced [kʰɛ̄ːn]; Northeastern Thai: แคน, pronounced [kʰɛ᷇ːn]; Khmer: គែន – Ken; Vietnamese: khèn or kheng) is a Lao mouth organ whose pipes, which are usually made of bamboo, are connected with a small, hollowed-out hardwood reservoir into which air is blown. The khene is the national instrument of Laos.[3]
The khene uses a free reed made of brass and/or silver. It is related to Western free-reed instruments such as the harmonium, concertina, accordion, harmonica, and bandoneon, which were developed beginning in the 18th century from the Chinese sheng, a related instrument, a specimen of which had been carried to St. Petersburg, Russia.[citation needed]

he does this interesting rhythmic stuttering technique, I assume just with embouchure control, that is really reminiscent of electronic micro glitch/repetition effects
