Their live vocals are wonderful here. Babymonster are incredible. I especially love rami’s voice, and I think she could have even more stable live vocals if she made sure always to sing her high notes in her singing voice not her speaking voice. Love you rami!
Do you hear Yeri and Irene on the low notes?! Seulgi and Joy with their bright and unique vocals and Wendy with that power and control. The three of them have the best vocal colors that blend beautifully when they all sing together.
Do you mean how they extract the live vocals? If you do, then they the recorded audio of the song then sync the live performance with the inverted recorded audio to remove the recorded audio and leave only the live vocals
