Following the debut of Cube Entertainment's first unit group, Trouble Maker, the second unit group has been chosen to be 4minute's Gayoon and Jiyoon! On December 22nd, representatives of Cube Entertainment revealed that the two will be debuting as a unit after the release of 4minute's comeback album and promotions next year. As 4minute's main vocalist, Gayoon is known for her exceptional vocal talent, and has already participated in a number of OSTs herself. Combined with Jiyoon's talent as 4minute's second vocalist along with her experience on 'Immortal Song 2', the two will be showing a new charm and image unlike any seen before. The representative stated, "Gayoon and Jiyoon's vocal styles are completely the opposite of each other, but when combined, creates a beautiful effect. We're currently considering them as a ballad duo. There isn't a name for their unit yet but our company has taken to calling them the 'Double Yoon'." Stay tuned for further info!
