This is one of those performances that people saw back when it happened and realized BTS was DIFFERENT. Like the energy, the sincerity, the FUN they had on stage, the charisma they had as individuals and as a group...this was something so new and unique and powerful. They were known as performance monsters since they debuted and this was just like a show and prove for them.

V doing the aigoo voice (🤣) and Jimin losing it with laughter so hard he couldn't sing or stand.😂🤪💜💜

They performed this song at KCON LA in 2014 when they were complete unknowns and ended up blowing the audience away. Check out that live performance when you get a chance. Edit re Jimin’s shoulders: have you not seen the dance battle with BLOCK B?! 😱 Watch it!!!

What's crazy to me is that this song was released in 2013, the year they debuted and it contains lines like: But what will happen if Bangtan Seonyeondan rises? My feet sound the alarm, announcing my entrance to the K-pop world Who are we? The rising BTS Climbing to the top is a matter of time, the first block of the dominos has been pushed down If you don't know us, get to know us well And they did it! They climbed to the top and became bigger than K-pop itself... they couldn't know back then but the believed in themselves and they made it That song is a self-fulfilling prophecy

I remember even Eric Nam admitting that they were MONSTERS back from the begining. They were actually getting a lot of attention as newbies everywhere except Korea because they always were 5 steps ahead everyone in the industry doing their own ish. Especially performing and enjoying music WITH army not for Armys. And it always stayed that way.

Yeyyyyy!!! Finally Attack on Bangtan... This is one of my early favorites BTS songs.

love this song. now it's time to react "boys with fun" and watch V become the choreographer guru 😆

Guy in the red pants at the beginning is their choreographer Son Sung-deuk 💜💜💜💜💜💜💜

Jimin does have nice shoulders, yes. but if you want a really big shock look up a pick of his thighs. phenomenal indeed. these kids are real athletes.

You know how JK loves to inmate people. I swear when he is rapping his first verse he sounds like Seo Taiji. So good! This is such a fun get up and dance song. Love it. Thanks for reacting. I can’t wait to see your dance moves. 😉 💜🫰

Now you can see why they are on top .. no matter how tired they are, they always give 100% .. unlike other people who don't care that the audiance spent a lot of money to see them perform, BTS cares a lot about those things so they give their all every time .. thats why we love them so much .. good luck with your dance class John .. by the way Jin is going into the military tomorrow.. good luck to my favourite guy 👍👍🥰🥰🥰💜💜💜💜💜💜💜💜💜💜💜

Yaaaay, Attack on Bangtan!!!! Such an old song but always a goody! The thing they have on their chest is their names, I think they used that so camera men knew who to focus on when filming or something like that but not totally sure. Suga always a mood, lol, gotta love that man sassiness.

And the live version, on top of everything you said, they are singing in Japanese. So amazing 🤩

I love this song so much. V goes off and chaos erupts! John you don’t need to learn to dance to have this much fun 😂. 🏆for Jimins shoulders, which we rarely get to see anymore 😂🤗💜🇨🇦

One of my favorite songs. This was in Japan and V was total crazy and happy. If I remember correct the version you watched is from Beijing. There is a better version from Nanjing. Search for it BtS Epilogue Nanjing. For almost the whole song he jumped on JK's shoulders who carried him piggyback and then on his shoulders. Nonstop laughing. And he messed up JK's hair while dancing in another song. Because of teasing him he made a few mistakes in dancing and almost passed out laughing. And the Baepsae performance was... 😅🤣😆 J-hope was the best, but Fancams shows that V improved a lot 😁💜 JK is a beast on stage. He isn't the leadsinger for nothing. RM said once that despite dancing he has the most stable voice. Greetings from Germany 💜

All of them can compete with each other for every other voice and on any given day, any vocalist can win. But when we talk about that ocean deep voice or that rock growling voice.. no one stands a chance. V remains undisputed ! His vocal range astounds me. Imagine this same singer hitting those higgghh notes in stigma. His growling made this song for me ! 💜

Oh man, you gotta check out more of their older stuff - the dance practices are absolutely in sane! They were much "harder" then, I think. And yeah, JK is THE JK. He's just the best. 💜💜💜

This song gets my happy no matter how was my day hehehe This was in Japan and V was tooootally crazy that night 🙂

V is especially strong dancing here. As he has refined his style we have lost some of his boisterousness - but we've gained grace and sexiness. P.S. In dance practice they often wear their NAMES. RM is often the only one using Roman letters. See Mic Drop Dance Practice. Surprise your wife by dancing like BTS! In 2017, in England, at my niece's wedding - the 7 groomsmen danced "Boy With Luv" at the reception!

This was the "look at my arms" Jimin era, hahahaha. This choreos were so powerful. So much energy. Was this the studio they always talked about with water leaks? They have their name tags. The did it until everybody could know their name, and they did it, hahah. Yesssss, go John!!! BTS makes me wanna dance too! I am from the robot club too, haha.

12:39 Their names, for camera work etc for the performances. 지민 = Jimin, J-Hope: 세이홉, Jungkook: 정국 , Suga: 슈가 , V: 뵈, Rap Monster: 랩몬스터 and Jin: 진.

I’ve been wanting you to react to this. V’s voice in this performance is perfection.

No many how times I watch that live performance, I still can't grasp what's happening! 😂😂

V always so iconic... His growls are amazing

*happy dancing* THIS IS ONE OF MY FAVORITES EVER!!

Just like RM mentioned before when it comes to their live performances they will give their 101% or more because the audience (or ARMY) came and spend their hard earned money to watch them performed. He said he doesn't want the audience to go home after the concert and says it was a wasted 2hours of their lives. So they BTS must always give their best always. BTS is certainly worth the time and money watching them live.

Just want to say I love your reactions and thoughts John. You are so genuine and I love it . And then to piggyback on JK's amazing vocal control after jumping and running and still hitting his notes ..hes doing it all in Japanese. Not even his native language . He is just absolutely AMAZING!! As are all 7 of them 💜💜💜

I love this performance. They were wild. And the moment V caught the water bottle so effortlessly. His ability to catch things gives definite vampire vibes: kzfaq.infoy62pfOlC9ho

Not gonna lie, I have watched this particular live version of Attack on Bangtan to many times to count. It is one of my favorite "hard" songs next to ON. And can I just say....am absolutely in love with V's hard raspy growls!!! I wish he would do them more. Love his voice!! If I remember correctly, this is from their Japan Epilogue concert from 2016 (I think) in Kyoto, Japan (not 100% sure if that is correct) This is also the concert of the infamous and iconic No More Dream Dance Break....but I digress...they go so hard on this song it's just amazing!! Thanks for the reaction!! Have a great rest of your week!

The “backup dancer” in the maroon pants is Mr. Son! You JUST now are noticing Jimin’s incredible body parts?🤣🤣🤣

The beautiful thing is that the boys are having fun, bot trying to be perfect ax nd just enjoying and performing as they were. One thing you cannot hate, is howwww cute they all are lol..

They have their names taped to their t-shirts because the cameraman didn't know their names. I remember RM said one day they won't need that because people will know their names.

Legit SO FUN! LOVE THESE BABIES

I’m sooooo glad you finally reacted to this song. The dance practice is insanely precise. I love it!! But the live omg it’s the BEST. Taehyung went off with the growling🔥🔥🔥 JK and the power slide into the falsetto is perfection. That whole concert is 🔥🔥🔥🔥🔥🔥 Can’t wait for your dance practice videos😜

I love love this performance. They were wilding! Also that moment where V just caught the bottle Jin tossed at him - wow. Here's a compilation of V catching stuff: kzfaq.infoy62pfOlC9ho Definite vampire vibesa😅

that's why he's the main vocalist

This was released in 2013! BTS have earned the right to have been gotten a GRAMMY! These guys are very unique in everyway possible. NOBODY is doing concerts the way BTS has done them. We need to push their music more and more to earn this award. So many others have not done a oz of what BTS has given to us in 10 plus years. They really need to be HONORED AT THE AWARDS for ALL THEY HAVE DONE and still DOING TODAY. BTS is so humble, talented, kind and so awesome. STOP HATING on BTS. GIVE THEM THEIR WELL DERSERVED FLOWERS when they return from their commitment. Again, doing all the things to help their country and us.

YESSS! That whole concert is legendary! I don't know what got into them that night but they went nuts! 😂 I totally needed this today. And kudos to Meg for including the second practice video! 💜

This is one of my favorite early ones! I think someone already mentioned, but in the first practice video, the man in the maroon pants is Son Sung-Deuk. He's their performance director (basically head choreographer) he's been with them from the beginning. I love how they just have so much fun on stage.

The signs they were wearing during the dance practice just had their names in Hangul on them. Hangul is the Korean alphabet. The camera operator didn't know their names, so they had to wear their names so the camera operators knew who to film at various parts in the song. I think that live performance was from a muster and they did a lot of their old songs at that time.

I was just watching this last night again LOL this would be your typical chaotic BTS live performance. Man! love them so much 💜

So you can start learning their names in Korean, they are like this: RM (Has no Korean words so they use just the letters now but back then they used 랩 몬스터 that means Rap Monster, Jin 진 , Suga 슈가, J-Hope 제이홉, Jimin 지민, V 뷔 an d Jungkook 장국.

Thank you for this reaction John, I love watching their early work because their baby faces were so cute and then they turn savage. And Suga leaping over one of the dancers! No downshift for these boys no matter how many songs they have already sung. JK rapped a lot more in those early songs and his voice was always stable, he has perfect pitch and even in their Run BTS and various travel series his vocals were always stable even while messing around. All the best for those dance lessons, find your rhythm and go for it! Btw, our Moon reported for his training today, our love go with him and prayers for his continuing safety and welll being.

The paper with the hangul (Korean) writing is their names. In the beginning they had to wear these name tags for performance practices so the camera operators and crews would know who they were.

Yes Jimin's shoulders. Any time you see them it's goals, there are a behind the scenes from recording Idol, for Fallon's show, where he has taken off his shirt and only wearing a top and wow. But Jimin is so underestimated by people when it comes to athleticism, strength and even other dancing than contemporary. I mean just look at him in any athletic competition or when it comes to strength and muscles, it always him and JK on top. In the newer Flying Yoga Run ep he sat with his legs crossed and climbed up the flying yoga hammock using only his arms. He is ripped and athletic. But it's that thing that he is mostly behaving cute and sweet and therefore can't be strong thing people have in their heads. They don't wanna see- or are so so caught in the thought that strong and muscular must be more masculine and hard that they think he can't be strong and somehow they miss that about him. They often think it was just back in the early times but no, he works out and are so strong, they would know if they just listened to BTS and Jimin and watched full material, vlives etc. and not just compilation videos.

One of my best faves forever

Omg I'm soooooo proud of you!!!! I bet you will be awesome.

I remember when BTS were preparing for their FIRST major concert ANYWHERE. They were so nervous, but Jimin was the most scared bc he didn't like his voice. I was so worried about Jimin, but they all did great 👍🏽! Also, back then Jimin was thick and muscular. He really loved showing off his body to the point that things started getting out of hand and the group intervened to put a stop to it...this was around 2014.

yes, love to see you dance. back you 100% . 💜💜💜💜💜💜💜

I’m the first one here this is a first

The dance practice is the Korean version and the live performance is in Japanese, which means the rap and song are in Japanese.

Anytime people ask how they are so close and dedicated to each other.....go back, start at the beginnings, and see where they started.....the comradery has been built from years of what is shown in these videos. From the very humble dance studio, the very young ages, and their being very new to each other, you can already see their going to be a force to be reckoned with! They all slept in the same dorm room on bunk beds, JK was only 15 when he started, going to middle school, Suga was still working part time delivery jobs as he had no family support at this time, they really were their own support system while chasing their dreams.....No one in the music industry is a greater representation of the quote"blood, sweat and tears" is what got them to where they are today....so proud to be an ARMY!💜

Son Sung Deuk (the BTS Performance director!) is the guy in the red sweatpants btw. Background dancer as needed back then.

This is the moldy basement practice room. The mirtors would fog up. Often had to mop floor to dance.....

You need to check out their concert in Paris where they had a water fight on stage whilst performing. It is hilarious and so good to see them comfortable and truly passionate about their craft.

Love V's growl and his impromptu dance moves.

One of the most fave old BTS’s song!!! Everytime i miss them i listen to this song 💜💜💜

LOVE, LOVE, LOVE this live performance!!!! Easily one of my favorites. 💜💜

wow so crazy how much they have improved vocally! imagine them perform this now

This was awesome ~ I needed this so much today. Love Attack on Bangtan, especially the live~ You stopping the dance practice to praise Jimin’s shoulders made me laugh so much, but also..same! He DOES! And I think it’s amazing that you are going to take lessons!! I love watching dance and also love to dance myself. I’m not trained..except maybe by all the artists I grew up watching. I'm excited to see you realize you can dance~ 😁💜

I am so excited you are going to try dancing out! I trained for ten years in dance when I was much younger. But the most important thing is to just enjoy it. Dance like nobody’s watching as the old saying goes. I don’t really remember how perfect or imperfect my dance steps were. What I do remember is the feeling of freedom and happiness that came with dance. Just enjoy it. You understand music, so you are already a step ahead. (Pun intended.)

Holy crap! A dance class is a bold move!

A note. Trivia. Their choreographer is one of their backup dancers. When it starts he is on the right in maroon red pants in the back. Then he does move to the front row doing kicks on the floor. Also. If you notice the backup dancers are not young trainees. They are older dancers...who worked for the choreographer. In the beginning the choreographer would use these guys to figure out the choreography. And they would dance and show and teach the choreography to the guys.

Yep. That happened. Live. 🥰

This is a gem!!

Love this one! Boyz with fun is another fun live performance you need to check out

thanks, John! It was a great way to start my week! Borahae! 💜💜💜💜💜💜💜👀

those papers on their bodies are name tags for camera directors during music shows/live performances rehearsals usually, so they know who is who and who, and who to focus on during their singing/rap parts.

Yea now this is a reaction!!!of all their concerts I would have loved to be at this one! Can u imagine the whole place was partying 🎉

I think they have their names on their shirts and they might send the practice in for shows or planning stages, so that the camera operators and directors can have an idea of what shots to get and who to focus on.

Jimin agrees his shoulders are amazing because they repel clothing and he’s always shrugging off his jackets etc. YAY dance class! I miss it I need to start dancing again. When they have signs taped to them that almost always means they are practicing or about to do a TV recording and the signs have their names so when they go on stage the stage manager camera director each can make notes about who is in what part of the stage and who/where to pan in on. This song is an eternal favorite and for being one of first songs it encapsulates their talent, fun, silliness, energy just everything we love about them. They let everyone have time being highlighted and the lives are always epic.

LOVE all of this! Favorite J-hope outfit! Dance your heart out!

That their concert held in Japan and they sang the song in Japanese version.

Wow! I’m watching this on a Monday too - and I’m in Sweden. From my perspective you are an authority on energy, because you sure do have it! You have quite rapidly become one of my (few) favorite responders. I feel, from deep in my heart, your dancing challenges. My parents and my 13 month younger sister were incredible dancers. And then there was me. My first male friend, who was a musician, pulled me out onto the dance floor for the first time I was in a club, assuring me that “everyone can dance”. …only on a later occasion to pronounce “you don’t dance very well.” Still we were partners for 17 years until he died and we went dancing nearly every weekend.

The back up dancer in the 1st practice wearing black tee & maroon pants..he is wearing white tee & black pants in 2nd practice is Son Sung-deuk, BTS choreographer

One of the funniest performance ever 🤣 that niko niko ni was cute 😂💜 the choreo?? Hello! that freaking synchronization?😳

Omg... Attack on bangtan.....

Stop!! I LOVE you're taking a dance class!!! Can't wait to watch! Enjoy the process, it's so much fun!

Their songs are amazing. They believe on themselves always, and they took us to enjoy the ride together. So grateful for having the Bangtan Boys. Borahae! (Have a safe adventure JIN.... we're waiting for you)

ahhh,, so touching to see Son PDnim always dancing with them in their early debut days... Look how they all (BigHit Fam) become so "BIG" now.. Son PDnim is always proud of BTS like a father do for his own kids. Time flies so fast, BTS has even become the coolest uncles of MOA & HOA (Son PDnim children).. really BigHit = Family 💜♾️

Song Sungeuk loves the boys. I would say choreography is his gift. Very early on he was touring countries giving choreography work shops himself. He is in Maroon pants and baseball cap here. Often you will notice him on stage either behind center front...as in DANGER dance battle block B. Other BTS choregraphers Sienna killing it with On and J-hope lalapalooza. Siennas Dance group, the lab. Anyhow I adore Brian Puspous go to Midnight Masters , Snowglobe Studio.

If you wanna see the performance with the full dance choreography, I believe you can see that on their comeback performances of this song.

I heard that they trained on treadmills while singing which is why they are able to run all over and still hit those notes just incase no one told you already

If I had to show someone a video that "encapsulates BTS" I would show them the Live version of this that you watched! Like SERIOUSLY! it's just so much chaos and amazingness and I love it so much!

Awww that’s precious you will be a good dancer and your wife will appreciate your efforts 💜

👏🏻 👏🏻 wow 🫡 can’t wait for your dance journey 😃👍🏻 and I’m enjoying your Bangtan reaction as always. Stay blessed 💜

I absolutely love it when they laugh while singing 😆

Kpop dance class??? Live performance in Japan as my country. They were singing in Japanese.👏👏👏👏👏👏👏

i love them all, V is my bias ugh 😍

One of my favorites from them. This is on my work out Playlist

This video made me smile after a long Monday so thank you, John! #shouldergoals 😆 Loved that you showered my boy Jimin with compliments! This song is an oldie but a goodie 😁 It's so amazing that BTS has inspired you to take a dance class. Enjoy!!

you know it's an old bangtan video when you see *that* Jimin 😂 thanks John for bringing a smile on my face and even getting a laugh out of me with the compliment on jimin's shoulders. I really appreciate it at this time...

this is THE SONG if you want to get hyped out.. this was my go-to song if i want to wake myself up from being gloomy.. so glad you already saw it!

Can't wait to see you in dance class. You can do it! Remember that Suga and RM both said they couldn't dance when they started with BTS and look at where they are at now🙂!

One of my favorite dance practices and live performances!

2025 comeback.... would it not be awesome if this was their back to life fun. Then Run BTS and a new one for a taste of future BTS

OMG John dancing!?!??! This would be amazing! John - Don't know why, but I picture you as an AMAZING BREAK DANCER. You should give it a try! ;)

I haven't seen this dance practice before. Those signs they're wearing are their names. CONGRATULATIONS on starting your dance "career"...you wife will be so surprised. Can't wait to see your progress. One of the ARMY groups will begin dance lessons - learning BTS choreos...old and new...even for people like me with two left feet🤣😂

Those are their names taped on their shirts...not exactly sure why but you'll see them in a lot of their earlier dance practices. And amazing news on the dance lessons...everyone can learn to dance. You already know rhythm and music so you have an advantage. They run on treadmills while singing, that's how they have so much breath control.

Love the live performance for this one. The energy is just insane! I also love that you are going to take dance lessons - it's good to do things out of our comfort zone once in a while. Have fun!
