Here is a very passionate drum group from Korea. Kim Duk Soo playing the hourglass drum in this video was the founder of this genre of traditional Korean drumming called Samul nori (Samul meaning four objects and nori meaning to play). The group consists of the Kkwaenggwari (a small gong) a Jing (a larger gong) the Janggu (an hourglass-shaped drum) and a Buk (a barrel drum similar to the bass drum).
