@Musicappreciator7 I know I've seen live vocals in the stage performances from similar shows in the past.
But I don't remember if the live vocals were in the early rounds or the later ones.
It's possible that we'll get live vocals in the later rounds, after they've given the less-experienced trainees a little more time to settle in. I hope so. Singing live is an important ability to have for anyone who's genuinely going to debut.
