South Club vocalist Nam Tae-hyun's commentary film and free Lyric image of the new song 'Rock Star' were released on the official SNS on August 29th and August 30th at 6pm.

Nam Tae-hyun, who created songs for the existing South Club and announced his presence as a singer-songwriter, said, “This new song is very unfamiliar to me because I received songs from producers. I did not compose myself, but instead received a song and started working on it, but I wrote the lyrics. Maybe that's why I don't know how to do the stage. The existing songs were well understood because I made them, but the new songs are focused on grasping the intentions of the producers. It is bright, but when you look at the lyrics, you try to overcome something and think positively. It's a song with a message like 'It's hard days, but I want to be a star in them.'”
