After 10 long years of working underground, the four members of a new male vocal group, 'I STORY', have finally made their debut with an impressive single titled, "The Inside of My Mouth is Burning." As previously reported, I STORY is a four-member group that's fought hard to make their debut in the mainstream industry. Leader Nam Chang Woo and Lee Dong Wook were members of an underground group called 'Urbaniq', while Noh Young Ho and Hyun Joon were gearing up for solo debuts. They came together as a talented quartet, with Nam Chang Woo acting as the group's rapper. The group shared their hopes in attempting different genres in the future, and described themselves to be a multi-vocal group in style. They'll be releasing a soul-focused album annually, in addition to their other work. - 01.
