In August 2012, the siblings auditioned for the second installment of SBS reality survival program K-pop Star as Akdong Musician. The sibling duo finished in first place, later choosing to sign under YG Entertainment as they were the only label from the three to provide them the creative freedom they wished for throughout the show, believing their artistry would not be restricted or altered.
