As Umji said at the beginning that they've been on it's live before during the loveade comeback. They've performed bop bop, loveade, and red sun! If u haven't watched it yet, i highly recommend to check them out cause as we know that there are highnotes in those three songs :D
I agree that this live band version sounds even better than the studio version. They sing with clarity and strength, yet their voices carry more personality live. Umji's golden voice, SinB's slaying styling, and of course, Eunha's gift - her breathing...LOL.
