As previously reported, Akdong Musician made their very first appearance on the May 30 edition of 'Yoo Hee Yeol's Sketchbook'!

These lovely siblings gave a beautiful acoustic performance of their first title track "200%" and then Chan Hyuk took the stage by himself for a dance solo!  Not only does he have the musical capability for composing and singing songs, he has the moves, too.

Check out the performances below!
