The Loloko Chor, named after a local tribe, comes from Renho Village in Nantou Country, located in central Taiwan. Founded in 2002, this youth choir sings traditional aboriginal polyphonic harmony that was passed down from generation to generation within the Bunun Tribe. The rich and complex harmonics af the Bununs have been in existence since primordial times. Even though the choir members never received formal vocal training of musical education, they have been singing passionately with their pure and natural voices, now singing at invitations around Taiwan.
