Jung Hyung Don said, "Our hair and makeup are acoustic.  We just put water," revealing how they got to take part in the acoustic festival.  He said to Akdong Musician, "Don't look at music lightly, don't fulfill your dream by connecting it to money, but it looks like you will succeed if you put messages in your music."

Defconn added, "You should look at us and learn about fashion," although there are undoubtedly plenty of fashionistas at YG to teach them that!
