Famous producer Kim Chang Hwan finally debuted the fruits of three long years of labor on today's episode of 'Inkigayo'! His very own boy group, N-Train, held their debut showcase on May 25th and revealed that they were determined to be acknowledged for their vocal talents alone. Their debut track, "One Last Cry", is a soul jam with lyrics about a man reminiscing over a woman who he can't seem to forget. N-Train explained, "Idols are usually known for releasing dance tracks with strong beats. We hope to differentiate ourselves by emphasizing an R&B style. We're confident, but we won't let it get to us, especially since we still have much to learn in order to grow as artists who leads Korean music." Check out their debut below!
