I don't really understand this sentiment, yes Jihyo is a power vocal and all round great singer, but all the Twice members are now good singers there's plenty of evidence to that fact. The idea that the other members are just dancing around lip-syncing and just letting one member sing is ridiculous. Last world tour they literally had a live band in addition to the solo stages. The only parts I notice they don't do live is some of the lesser ad-libs. You can go look up MR removed videos: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6kMmbSrDYk4.html

​@@zer0_cool I didn't say anything about lip-syncing (they aren't) or the members not being good singers (they are). But backing vocals doing a lot of heavy lifting is standard in K-Pop concerts, and you can often tell when they're present. Even a vocal power-house like Mamamoo often do it. It's not an indictment, and I don't think MR removed contradicts this (although the source video of your example certainly sounds like it has a less powerful backing track than this does). The fact that you can more clearly hear their (perfectly reasonable) vocal imperfections and see their faces straining and exerting during the Killing Voice, despite being in a controlled environment where they're standing still, significantly more than in this uncontrolled environment where they're doing choreo, have blank faces even during the challenging bits, the crowd's loud, and the audio is virtually studio-perfect kind of tells you everything. I'm not suggesting that they can't (or never) do fully live, I just have doubts that this is an example of that (and it's common in K-Pop concerts not to). I'm not making an assumption about Jihyo based on some perception of vocal superiority or something, I'm just saying that I've seen more examples where Jihyo having fully live vocals during concerts w/o a backing track is obvious, because you can hear her voice actually slightly faltering and quivering once in a while, as well as hear her breaths (and off-the-cuff improvisations), which is what you would expect from something fully live. There's nothing wrong with it, it's just worth clarifying in response to his bewildered comment about stability.

K-pop concerts, in general, don't fully live for obvious reasons. In Twice japan concerts, most of the time, the backtrack is low, so it's really easy to notice when they're lipsyncing or just not singing (well, at least to me lol). Misamo showcase was basically the same, you can easily see when their voices are overpowering the backtrack and when they're not. Talking about stability, even with the backtrack you can easily hear the breath pauses that they do (in this performance), so the backtrack is not that high and it's easy to notice when it's the backtrack sound and not them (you can notice it by their tones changes and textures to). I would say their voices are overpowering the backtrack 90% of the time in this performance.

Even Jihyo, Nayeon and Jeongyeon parts have backtrack, not just because it's hard parts or something, but most of the time because of the harmonies that they do using their own voice for ad-libs. Mamamoo is a great example of an extremely powerful vocal group and they still use backtrack for harmonies, because it's basically impossible for you to do 3 diferrent tones, with different textures and highs at the same time lol

Talking about my experience, when you see they live it's way more easy to notice these things. The problem with twice concerts videos is that they usually try to make the cheers lower and it ends up lowering the girls voice too. That's why the backtrack can sound too loud, because she's the only thing that don't suffer any editing.

Back when they debuted with the cute concept yeah you could see and hear it was mostly men but nowadays I think even in Korea it's pretty close to even, at least based on what I've seen from videos. But yeah in US it was also mixed.

here in brazil is mostly women, but still A LOT of guys

they are the vocal lines of this group
