Evidently Bundun is famous for their bamboo bands and devote whole strands of bamboo to the instruments. This is only a small portion of the band. This is my first attempt uploading a video. After viewing it I see it shows some of the song, but you can get the idea at least. In some bamboo bands they pound the tops with flipflops or something. In this one they actually pound the bamboo on the ground. It's better to have hard packed ground for a deep sound. The language is Bano (I think - could be Kote).
