After releasing his comeback album and a MV for his title track, Outsider finally performed his first comeback stage on Mnet's M! Countdown, performing Acquaintance! With the orchestral background, his speed rapping was unbelievable. Check out his rapid performance below! It's been a while since I last saw Outsider perform. Mostly recognized after his hit song Loner, he's one of the best rappers I have listened to. It's great to see Outsider back!
