Love how honest Mark is with his opinions. He's not afraid of getting shot down.

SM is so confident in everyone's talent they aren't afraid to show their live recording sessions.

doyoung, haechan and xiaojun's high notes are insane. they nailed it so effortlessly, it's crazy. also, jungwoo's flawless voice, fits perfect anytime everywhere.

Mark and Haechan definitely have their own mic in their throats. They’re too talented…

Can we talk about xiaojun being shy about his vocals to doyoung? He’s so cute! 😂

Doyoung cracking his knuckles and saying "I'll make this happen. I can do this." So full of determination and leader vibe. Also showed how much pressure he felt being the senior in this group. I am proud to stan this man, and I am grateful to everyone who showed this song love and support.

Yangyang and Jaemin even Shotaro really came to sing 1 line and the rest adlibs. The bitter sweet feeling that I've been feeling since it was released is always there.

Shotaro must have had so much work behind the scenes over the past year, with learning a new language, taking vocal training lessons, still maintaining his own dance schedule out of passion, adapting to a new country + culture + social situation, and also preparing and promoting new songs + choreo with NCT U. Plus with all of that, he’s also likely preparing for a new NCT unit to debut and all the work that goes into that 🥺🤯

i love how mark always voiced his opinion whenever he's in the recording room, he knows how to make his verses sound better.

i find it touching that doyoung was there for shotaro during his first recording and then one year later he’s still there for him🥺

HAECHAN'S VOICE IS JUST REMARKABLE 😩 who ever put Haechan, Doyoung, Xiaojun and Jungwoo in this song, we love youuuu! the vocalsssss ✨✨✨✨

Haechan literally sounds just like the studio version, you don't even need to touch up anything wtf

I'm sure haechan and mark has their own blankets or rooms in the recording studio. They recording more than 50 songs in 2021 alone.

Doyoung is so professional in the studio. He isn’t afraid to show himself struggling and overcoming it. You can also see the relationship he has with the recording producers, how they both exchange opinions on how to record

Haechan is not even my bias, but I'm just so impressed by how incredibly good he is, he surprises me with his voice in every recording video

1:12 the way he practiced a lil and then walked up to the mic and ATE THAT UP AND LEFT NO CRUMBS???? HAECHAN NEVER FAILS TO AMAZE ME

Haechan’s vocal tone will never be out of style.

XIAOJUN IS COLLECTING EVERY NEO WITH HIS CUTE PERSONALITY... I WANT TO HUG HIM TOO.

Haechans voice is literally ripped from the studio version WHAAATTT??!! His vocals are insane

*Doyoung* cracking his knuckles and saying, *"I can do this"* just shows how strong and determined he is. They all did an amazing job, I applaud *Doyoung, Haechan, Jungwoo, Mark, Jeno, Xiaojun, YangYang, Shotaro* and *Jaemin* 👏🏾👏🏾. I love *YangYang's* hoodie, it was the *WayV* logo on it

Shotaro and Yangyang did amazing! They've improved so much, so proud of them.

haechan is a genius fr the way he manipulates his voice will never fail to amaze me.. every sunflower looks forward to these recording uncuts because he slays in each one i’m so proud of you haechan

17:20 I love how Haechan was surprised when they asked him to sing this part in falsetto, like he was sure he had to sing it in mixed voice or something xD

Haechan’s voice is insanely unique and beautiful. It almost sounds like they use voice effects.

Mark's true artistry and passion comes out in these uncuts. He’s self directing himself, monitoring the recordings and giving out opinions on how to make the song better. Like his idea to include the laugh in his verse was legendary, he knew small ideas like that would make the song shine more. I loved it when he told the producers that he enjoyed the main recording more than the backing and that he think the main should be the loudest. It really showed that he has an ear for musical details. Also can't believe he also wrote this iconic verse. What an true artist he is

Mark directing himself and giving opinions to the producers really shows how good he is. You can see his passion for music. He's literally good at everything he does. A true artist and ace

1:07 - My favorite part! Haechan's vocals are just stuck in my head!

18:20 When Xiaojun asked what Doyoung gave him and Doyoung was like “it’s candy “ then he mentioned “I heard Pavarotti ate this to “ . I didn’t see anyone else comment on it cuz maybe it was too quick to catch but doyoung is referring to the legendary Italian opera singer Luciano Pavarotti. the secret to why our boy Doyoung is so vocally talented is cuz he learning from one of the greats😭

I love how Mark being so professional in recording booth. he's not afraid to speak up about his opinion. Mark only gives the best

We get another Doyoung and xiaojun moment. It's really adorable

haechan.... mr lee haechan..... the VOCALIST that you are

Haechans RAW VOCALSSSSS, always good, DY and Xiaojun too!!

Since no one is talking about yangyang, shotaro, jaemin i wanna add they did an amazing job.

When haters said that NCT's vocal is auto tune, watch their behind the scene and you'll know how beautiful their voices

HAECHAN’S VOCALS IS SO GOOD IT BLOWS MY MIND EVERYTIME

This proves how Haechan is an awesome vocalist cause he sounds like how he does in the song and they can do whatever they want with the recording and also in the other songs he sounds like how he records it especially hot sauce, this is why he's a main vocal

Haechan being a pro in recording studio make me always amaze . He is normally playful boy but really serious when it’s come to work. Truely an ACE ,AlLL ROUNDER ㅠㅠ.

mark's professionalism is really just something else. he's so detailed and really wants to make things perfect, i love him for that. his inputs is just so good

I love how Haechan shows that he loves, enjoy, and explore his craft

haechan killing it in the booth once again, for the 50th time in 2021 let's go young legend 🐻

Mark Lee is really one of SM's gems .that boy's talent is unbelievable

haechan’s voice really is like honey, it’s so pleasing to listen to 😩

Haechan just has an insanely amazing voice my god always sounds exactly like the studio version even when he's live

18:26 xiaojun covering doyoung's ears because he's embarrassed of his high note is such a cute interaction between them

MOST OF THE TIME HAECHAN CAN BE SEEN VERY PLAYFUL TO HIS MEMBERS BUT WHEN HE STEPS IN TO THE RECORDING STUDIO, HE ALWAYS MEANS BUSINESS... HE IS REALLY AN OUTSTANDING IDOL!!!!

Mark just sing one line “let's play ball” at the beginning, but that song already sounds A BOP!

Haechan has one of the most beautiful vocals in SM and kpop I don’t get why they don’t try to promote it more? Covers, masked singer.. something

whatever song it is, Haechan will always deliverrrr

Haechan is too talented. I think SM really need to check if they are in the right mind or not cause why on earth you hide this talented man in the basement? You guys must be crazy! If I were you, I’ll promote Haechan like crazy since his vocal is so unique bruh!

Mark never dissapoint me. He's truly an ace. He's so talented

Mark doesn't fail to impress me every time with how professionally he sees the recording..... I mean the boy is out there throwing ideas and making efforts to make it sound as good as possible and he actually makes it.....also Xiaojun, Haechan and Doyoung make a hella amazing job with their vocals those boys' voices are out of this world.......of course can't forget about our Jungwoo, Yangyang and Shotaro that have made a progress in their recording....I mean Jungwoo's voice sounds so good in high notes, Yangyang put such a swag and strong feeling in his part and we can finally see our baby otter Shotaro being confident in his voice and actually doing a good job....last but not least our much lovable and extremely cute Nomin...what can I say about these two...their deep voices make their lines stand out so much and sound so good.....in conclusion Nct u rocked this song Amazing job guys😌💚💚

Shotaro's intake on how at first he didnt think the song was hip-hop but thru the recording he could recognize the style more is so interesting to me. he might be new to all the idol and singer stuff but he IS musically and rhythmic experienced because of his dance background. and you can clearly see how much he improved, even tho its only his second comeback. my boy probably worked hard as hell during all this time, so he obviously deserves to be where he's at (if there was ever any doubt). he's incredibly talented and hard working, he fits right in! lets not forget that! love shotaro 💞

we all know how smooth and sweet haechan's vocal is but something about this man in the recording studio makes his voice ×1000 more smoother it's like chocolate melted in my mouth

MARK and HAECHAN know their part so well..such pillars. Actually ALL of them nailed it. NCT are really built different 🔥

18:18 Doyoung is giving Xiaojun the candy/lozenge he uses for his throat, the one he heard Pavarotti used?? Is this not THE CUTEST VOCAL BONDING MOMENT EVER

8:08 the best decision Mark ever made.. i stg i lose my shit every time because of this part

Xiaojun flexing his vocals once again as he should. The fact that his raw vocals when hitting the high note exactly sounds the same is insane.

Haechan: like it's sung by someone who's bad This man knew how great and beautiful his vocal is

Shotaro's voice is incredible, as in make a wish he used an extremely low tone and in universe he used a higher tone, Shotaro is one of the ace of the 4th generation, a lot of love for our cute taro. 💚

7:25 Loved the way Doyoung waved at Xiaojun, he was so happy haha and Xiaojun saying that singing is difficult. I agree, it is. But you all did a great job here guys, you always do! I'm really really proud to be your fan

Haechan's singing skill improve so much this year. It's amazing bcs he always strives to better himself.

Jaemin, Shotaro and Yangyang had less lines, but sometimes is harder to do well a short phrase, and they nailed it!! Their voices added so much character to the song 👌😑

Mark is the definition of everything. He is so talented and you can saw that he always give his BEST💚💚💚

haechan HIS VOICEEE i can listen to him all dayyyy

Doyoung, Mark and Haechan proving once again why they are considered pillars of NCT---- *KINGS*

doyoung’s voice is so clean and sounds so elegant. i can listen to him all day.

Mark’s lil laugh at 8:25 after killin that verse has me howling 😂

haechan's voice is really good! OUR ACE 💚

Shotaro's korean is getting better. He's a fast learner considering that he had to learn korean while preparing for the resonance album. It's not easy when you're adjusting to new place & culture. Plus, he so cute🤣. I just can't help but to smile every time he speak korean. He's too cute😆.

Haechan’s vocals are amazing he has such a unique voice

xiaojun deserves more support from our side especially wayzenni! He's actually one of the most important vocals and he always sings tiresome high notes, his vocals are too beautiful not to be talked about!

Shotaro really improved so much since MAW in terms of rap and singing. He also looks more confident now and i think he's slowly discovering his strengths as an idol. He's developing his own color and i cant wait to see more of him in the future!! 🥺

Out of all videos of NCT, the behind-the-scene recording videos are my most favorite! This is where we see their vocal prowess and musicality! Main vocals Doyoung, Xiaojun, and Donghyuck showed us how cerebral they are when it comes to adjusting their tones to make the flow better and more befitting to the genre of the song. F*cking Mark Lee, once again, flexed on us hard his intelligence and passion when it comes to doing his very best. The guy is a perfectionist and I am living for his intense attention to detail! Jungwoo is more than capable to deliver main vocal levels of singing. He has the prowess to sub as a main vocal! It naturally comes out of his mouth... the sheer power of his super strong and melodic voice. Meanwhile, Yangyang has always been a hidden singer. The guy can belt out high notes and slay low notes. His aggressiveness and fluidity in pronunciation in every language he knows is a major advantage to him that if utilized and maximized to its full potential, can deliver very powerful and eargasmic output. Shotaro shocked me.... he can also do both high and low notes and I can see immense potential in him should he train more to hone his vocal skills. If he becomes more confident in singing in Korean, it will be over for us all. I cannot wait to hear him slay in a Japanese song where he can utilize his voice more naturally. Jeno knows the limits of his vocal capabilities and acknowledges it. I love that for him. He always slays whenever he sings in his vocal range and it clearly shows. Jaemin, despite being in this group with skillful vocalists, doesn't lag behind and shows us that he can keep up with them. There's something enamoring about his vocal quality-it tickles the ears and is very dangerously hot. With more confidence, I believe he will be more lethal than ever. These kind of videos show the naysayers how stupid their "noise" music allegations sound when commenting on NCT's vocals. The group members are clearly trained expertly when it comes to vocal training and their knowledge and skills show themselves in these kinds of videos. They all possess unique vocal tones and qualities that they (and the vocal director) cleverly combine to make their unparalleled and one-of-a-kind NCT sound that no other group can replicate. They are SM's gems and they are here to mothafucken SLAY!

xiaojun, doyoung and heachan their high note are no joke

I need haechan's "yeah nothing gonna stop us now"

Shotaro such a fast learner, how can he became so fluently on korean only one year after he came there.

Xiaojun's vocals are out of this world. And that moment between him and Doyoung was so cute

haechan's attentiveness to the details and wanting to redo the little bits he notices lacking is what i admire about him, he strives for perfection the best that he could and even adds his own color and suggestions into it making it his own

Shotaro is the freaking cutest when he's recording. Maybe it's just because I haven't seen much of him & I feel like I'm getting to know him more through this

Shotaro's so professional even though he debuted a year ago. All the members did sooooo well. My favorite content will always be the [Un Cut]..

Mark is made for rap. In every song that he’s in, when his rap part comes, its so relaxing

Haechan is always professional when it comes to recording. I look forward to his growth as a singer.

I love it when Shotaro said, this song doesn't feel anything hip hop in the demo. His experiences starts kicking in XD and yes Doyoung, Jaemin I feel your agony! TwT

and then there’s our Hyuckie being a one-take man wonder again.

SMent really hit the jackpot with Mark Lee. He's insanely talented and is good at all those talents that he has. You can clearly tell how passionate he is and how he's in his element whenever he's in the studio. Mark Lee ACE and All-rounder!

Mark Lee always giving his inputs and directing himself plus giving his opinions to the producers and adding his own touches.. He's truly an amazing artist. You can tell how passionate and dedicated he is with his craft and everything he does. I admire him so much

i have to be honest...my most favorite part is Shotaro's "let's play ball (2x), you're, you're my universe" it added up to the liveliness of the music and sums up my feeling on this song.

Mark came in and out that studio, he’s such a talent

Haechan just really has this something in him that i couldn't point out that is so special. Like really, he has this ability to draw everyone into him🤟

Haechan's vocals are definitely out of this world, his voice is heaven for ears😍😍😍😍😍😍

Xiaojun has the perfect combination between talent and cute personallity

ill always love haechan's vocal

i'm so surprised at shotaro!!!!!he has improved a lot!!!! and he's so tallented !! i hope we can hear his song more!!

Mark has already really reached that level where he knows the character he needed to show for every release they have. What more, he isn't afraid to bring forth his input and that's really admirable to be able to voice out, share, and contribute

Shotaro improved soooo much on his Korean, he's so confident now. Love that for him💕

Shotaro's personal vocal coach and supporter since debut KIM DOYOUNG

haechanie may be playful and naughty off stage but when comes to recording, he is a professional vocalist with high self-demand!

Vocal boys always stun me, haechan especially like, he’s such an incredible singer

Haechan is amazing as always!! He raw vocals always sounds like the finished track. I wish they didn't chop up the recording like this, I'd rather just hear all of Haechan at one time.

haechan is so amazing.. the way he always knows where to do a double take, where to do better, he knows when and where there is something to improve on, knows what sounds good, knows himself and his abilities well and sets high expectations for himself and thats exactly what makes him the great artist that he is today. he will never stop improving and only get better and better from now on until he will really become a legend in the industry
