On the April 15th installment of 'Sugarman 2', BTOB and Brown Eyed Soul performed on the stage. Rather than the entire group coming on the show, the vocal line, BTOB-BLUE showed up to go against the veteran group Brown Eyed Soul.
 

First, Brown Eyed Soul covered Ann's "One Sided Love" and they did not disappoint. Along with their perfect harmonization, the gentle guitar sounds in the background complemented their voices that simply put smiles on the faces of everyone. Meanwhile, BTOB-BLUE stepped on the stage to sing Lee Ki Chan's "Cold". As expected from one of the best idol groups in terms of vocal abilities, they performed in a flawless fashion. 

Check out both performances below and let us know which group stole your heart!
