Newly debuted group 15& put on a beautiful performance with Hanbit Bitsori Ensemble made up of children who are visually impaired.

The Hanbit Bitsori Ensemble previously made an appearance on 'Star King', the same program that 15& member Baek Ye Rin participated in as a guest years ago. As reported previously, Park Ji Min also donated her 'K-Pop Star' winnings to Hanbit, so the connection between the duo and the choir should come as no surprise.

The video shows the two girls and the choir singing 15&'s debut song "I Dream". The song, re-imagined through the harmony of 15& and the chorus, gives a newer, deeper feeling.

15& commented, "We got close to the Hanbit Bitsori Ensemble as we practiced and filmed together. We feel even closer to them because we got to know each other through music and song. We had a lot of fun singing and filming, and we promised to do a lot of promotions together from now on. We thank the choir for teaching us many things and leading us."

15& is also scheduled to attend the Hanbit Performing Arts Company's 'Music in the Dark' recital.
