In the year 1821, King Bodin and Professor Sau were obsessed with making the traditional Mohn hill-tribe drum. The story circled for a while that during the making of the drum the band broke up and King Badin’s child died. After a while their story was forgotten, 60 years later, teacher Duang inherited the drum from King Bodin. Many revered this drum as an instrument with a spirit that protects the musicians. If any musicians pledge their legacy to the spirit of the drum, they must honour their pledge or suffer ill fate.
