let's gooo

loontan

I HAVE ARRIVEDDDDD

Anya

Yayy pls do tnt, joyride, acai, blue lips

I’m Maya

James is a choreographer!!!! He is soooo talented

gi⁷ ❦

fun fact: james is the main dancer and has always looked up to jimin as his biggest inspiration 🥹 his mom is an ARMY and a jimin bias, and he once said that watching jimin perform “Serendipity” was the moment that made him want to become an idol

Sarah

This was so good! I don’t really stan Cortis but they are undeniably talented like actually insane😍

luiel

I’m so happy, I’m early😊

mia

I think you guys would enjoy watching some of there content or the making of their album since they do a lot of the producing, choreographing, and lyricism themselves they also are very goofy and love each other like brothers you guys would definitely find them entertaining.

nelle

AYYY finally dance practices!! so glad you guys finally get to see the full choreos, especially cause Jack really wanted to see the full REDRED dance lol. Just a heads up, the screen for the Fashion part is delayed, you may want to re-edit it before you post to youtube!

DDayTokki

I don't stan cortis but they are pretty fun :)! and they dance pretty good (i saw cannon side eye the camera with the "katseye" LOL)

luiel

cortis are self made artists. They create their own songs and dances.

E L

Wow you really like cortis huh

kim

as a dancer GO is easier to learn and to do, the most complicated one is fashion imo

Anna⁷

so one of the first groups that ever recorded dance practices were h.o.t, shinhwa (1st gen) and super junior (2nd gen) and the group that made dance practices popular was SHINEE (2nd gen)

Nanami's Wife

Hope one day for a shinee reaction, they’re all so talented

madii

Yall HAVE to watch the documentary its only 4 episodes and about 25 minutes a ep!

Mandyyy

I think you would like their mini documentary What We Want. It has only 4 episodes and it’s really interesting.

faith

for bts dance practices you guys should do some fun ones like the war of hormone halloween, go go halloween dance practice, just one day practice appeal version, 21st century girl dance practice halloween ver, etc !

Anya

The way yall were amazed lol soo good now I'm excited for BTS dance practice. Pls do run bts, fake love, on, black swan!

☾Joey

Cortis!!! They're amazing performers since day 1, its insane. And they keep getting better, somehow. Would love for you guys to check out any of their performances some day. You guys are also really good at remembering what name goes to which face! Curious to see what your guys’ bias’ end up being :)

I’m Maya

James is the main dancer and choreographer of their dances . James has choreographed dances for kpop groups, e.g. iliit, txt - deju vu, enhypen He is amazing despite his age

Etain

lmao the fact that McKay already clocked the main dancer. And Cannon, there is a killing voice version of dances, and it's spliced up just like you wanted LOL. It's cool, you guys should check it out. They do it for every group

SammiewiththebigT

They make their own choreography and produce their own songs. They’re really talented.

Corina Neagos

You should watch Cortis performing at Lollapalooza 2026, they killed it!

kai

their choreography is always so fun to watch

Teona 💕

I looked it up and it says It was Shinee that started dance practices with their song Lucifer but it also could’ve started earlier

Smiling viper

I know you guys had the option for old bands like from the first and second gen. It would be also cool if you guys could check out soloists or duo music as well. Woodz, Kang Daniel, Lay(EXO), Jackson wang(Got7),Akmu, Wonho and Ado ( a Japanese singer but she amazing vocalist)

lmnope._

I LOVE Cortis dance practices they're so fun lmao; I also recommend seventeen dance practices bc their amazing as well

S Moonchild⁷

is there a non-chaotic boy group in kpop? there are just ones controlled more. Seventeen, Got7, TXT, all guys are chaotic. Soloists can choose not to dance. Yoongi didn't want to dance, look at him now. All kpop groups unless they play instruments dance

E L

theyre so fun😆

loontan

gekpop dance practice when

Mandyyy

Now we have to wait an eternity to have the documentary reaction 😔

Sock

As far as I know shinee started the dance practices but bts did popularize the Halloween ones where the idols dress up

Kat

Ateez as well. I had never seen true chaos until them 💀

Hyeunrby

What's this lmaooooooo

jailynn!!

did cannon just say that he knows someone that's on dwts: the next pro???? dang everybody in utah know each other lmao

Leen 🎀

I love how Jack always does the moves 😭🫶🏻 James contributes to their choreography and him & Martin have a lot of freedom for the producing process it's insane how talented they are at such a young age. You guys should definitely check out their documentary on youtube i'm pretty sure it's only 4 episodes & you get a glimpse of their dynamic and how they came together which is pretty cool. Istg Go is such a bop like when I first saw it on Tiktok I was immediately hooked and was so disappointed when it wasn't on Spotify yet. IU does some moves but it's mostly just the vocal performance, groups are fundamentally performance oriented so you'll see them with the more complicated dance routines 🫶🏻 Their energy is so insane i'm actually gonna be seeing them in about 3 weeks in Barcelona for Music Bank along with some others and i'm sooo freaking excited 🥹🤍 Thank you for the reaction geks it was so much fun !!

☾Joey

About the tour controversy: Cortis went on a mini tour (only 10 stops, with all of the venues outside of Korea being theaters) that didn't follow the typical kpop concert structure. The biggest complaints came from people who believe that if a group with barely 40 minutes of music is gonna go on tour, then they should fill in the time with song covers, unreleased music, and costume changes. Cortis did not do any of that, and instead played some of their most popular songs 3-5 times. The only breaks Cortis took during the 2 hour performance was a couple minutes to chat with the audience. Besides that, it was just 120 minutes of hype. The controversy really only came from Korea (day 1), both from fans and antis. The fans because they were surprised and didn't have all their expectations met (idol culture is more intense in Korea—they even get disappointed if their fav throws up a middle finger to their friends), and antis because of course they want any excuse to hate on cortis. There were no complaints from any of the other stops, only praise from fans who know what they paid for and enjoyed it. Anyways, a lot of the “controversy” surrounding cortis is just performative outrage from people who don't understand how an imperfect rookie group is getting so popular.

Leen 🎀

yes yes pls omg I need them to react to Bakugo's theme song (TNT) hahah

keyla

been waiting for this one

Teona 💕

“It’d be cool if they did like a killing voice for dancing.” Well they kinda already do it’s called studio choom🤣

Jo

Ahh I’m so happy!!!!😝😝

S Moonchild⁷

true Ateez as well, P1harmony, boy groups do be like that

Hyeunrby

Red Velvet killing voice next week please!

Jo

“I feel like it’s the guy in the green” bingo McKay!!! James is the Dance machine in Cortis😌😌 all of them are goated tho

Jaden

Man Keonho can’t catch a break I totally forgot he was injured during their debut era and had to wear a brace and now most recently he broke both his pinky fingers?? and has to wear braces on both hands 😭 What could they be doing that he keeps injuring his hands?

Hyeunrby

Can I ask for NewJeans dance practice one day🥺

Beth Edwards

"I need to see some performances ASAP" they did Lollapalooza which was incredible BTW 👀👀

Jaden

You guys should check out Cortis’ Lollapalooza performance they did a few weeks ago💙

Beth Edwards

SHINEE was the group that popularized dance practices, which wasn't even intentional, because they had recorded them to watch back and see what they could improve on, and a staff member leaked them, and the kpop industry took it and ran lol

☾Joey

The only official position in Cortis is the leader (Martin, who also produces the most out of the 5). However it's pretty unanimously agreed that James is the main dancer. As others have mentioned, he's a choreographer. However I think it's worth noting that all 5 members are part of the creation process for their choreo! They all give their ideas and build on top of each other, with James being the one who organizes it. Also, while they have a lot of control and input in everything they put out (music, styling, videos, and choreo), they still have professionals collaborating with them + guiding them. I hope you guys watch their “What We Want” documentary soon!

Beth Edwards

If you want to see more of their interactions, they have a 4 episode documentary that shows their road to debut! Also, enhypen and TXT are pretty much ALWAYS on tour, and they're incredibly overworked. The reason Coers are a little upset about CORTIS going on tour is because they only have like 12 songs, and I think they're worried that CORTIS will end up like ENHA and TXT. THEO from P1Harmony absolutely hates dancing, but yet he's in a group that has insane choreography 😭 pretty much he just does his best and really enjoys performing for fans and with his members.

Emily fay

James was jung looks backup dancer once in seven

marsxiza

y’all should watch their documentary what we want

020125

thanks for the reaction! 💜 no bts were not the first to make dance practices however they were the first and popularized Halloween themed dance practices. I recommend gogo and 21st century girl. If you wanna know more about things bts popularized (trended) I recommend checking out “trends bts has created” by boracity 💜

Jess Min

Yes to all of these!!

Umbrella_Kat

Same. I've been wanting a SHINee reaction so bad!

Jo

Oh factsss!! I didn't even clock that 😅

saida

this was SO GOOD! thank you guys for reacting, i knew you'd love it! please do get your dancing with the stars friend on here, that would be such a fun watch! and to answer your question carter, shinee (taemin's group, under smtown like exo, red velvet and aespa) were one of the first kpop groups to post a dance practice to their song, they started the trend way back like 15+ years ago. not 100% on if they were the first, but i do know that they started the trend because they get referenced all the time on this exact topic.

saida

mckay, if you're part of a kpop company and you don't like to dance or don't wanna have to dance in order to make music, you tend to join a band (this is quite literally how day6 were formed and they are one of the most loved bands in korea and worldwide) or become a different type of artist, venture into different popular genres like ballad or hiphop. dancing isn't a requirement to be successful in the music industry in korea, but kpop is easily the most popular music scene so i guess it helps you access more opportunities in order to make it.

saida

OMG the halloween ones are SO FREAKING FUN!!

saida

was it not with their debut song replay?

Segen

cortis documentary orrrr performances 👀

Jo

In my opinion these are the K-pop boy groups/ Solo that are unmatched when it comes to dance 😊: Cortis Seventeen Stray kids Ateez Nct Taemin ( Shinee) Kai ( EXO) Taeyang ( Bigbang) 3J ( bts)

Jo

I’m not even a Blink anymore but I’m craving some Blackpink reaction😩😩 they were actually great when they wanted to be a group so please consider checking them out!!!

Tivy

You guys always pointing out Martin and James because they’re the ones you recognize most reminds me of when you first watched the BTS Netflix concert and were always pointing out RM and Jimin because they were the only ones you knew 😂 The leader and main dancers again too lmao

beannie

Can Cortis just let Jack join already

beannie

Shinee🚬...

beannie

need them to cover ring ding dong

Tivy

I love seeing how much more you guys have come to appreciate the dancing the further you’ve gotten into k-pop. It feels like now you’re just as excited to point out a cool bit of choreography as you are something in the music, especially Jack lol. It’s so cool seeing how the genre has opened up this whole other thing for you guys to appreciate beyond just the songs themselves and how much more you notice now!

NOELIA

This STUDIO CHOOM , RELAY DANCE

mo⁷

^^^^

Tivy

When it comes to dance, Taemin is considered the best in k-pop. He’s from SHINee (iconic and famous 2nd gen group) and you guys reacted to him in your first stream. He’s also an insane vocalist, so he honestly just has it all lmao

Eri

Cortis documentary next!

Snooze

And blood sweat and tears too

saida

oh my GOD BEANNIE YESSSS

Lamya

💗💗💗

Nanami's Wife

And Burning Up (Fire)! (Also Geks it's the Run practice from 2022)

Snooze

When you guys mentioned how chaotic these dance practices were, I couldn't help but think back to some bts dance practices especially war of hormone(real war version), just one day, baepsae and of course all of their halloween dance practices. Suga throwing it back, namjoon getting smacked right the face, them kicking each other, smacking each other's ass, v not being able to hold his laughter and turning purple with how hard he was trying not to laugh. They were on something different. About the cortis concert, I kind of agree with the initial criticism. They literally performed some of their song 3-5 times just to increase the duration of the concert and still the run time was pretty low. But I got to know that they learned from the criticism and started interacting more with the audience instead of performance after performance of the same 5 songs. It's always a learning process for every group. They make mistakes, get criticised and then learn from it.

beannie

you know ball saida🔥

nelle

carter’s natural aegyo is so refreshing 😍

nelle

they would be so shocked by the sherlock or lucifer choreo, i really hope they react to shinee soon!!

nelle

yes to all of those but throw in dionysus dance practice as well!

G. A

I’m in my 20s and the day I try to replicate those dance moves is gonna be over for me. Cortis lit been using 100% of those shoes and the room🥲

beannie

He also is like the weirdest/funniest human alive, they should watch some funny compilations of him lol. Shinee as a whole are just hilarious as well

G. A

Hope we get GoGo dance practice and the special heart event performance in octuber. Is a must 🤞🏻

YOSHITA

james is freaking beast...such a great dancer, so so talented

G. A

I have not watched a lot of their live performances but saw some tiktoks and wow 😨 Lollapalooza was 🙌🏻🙌🏻 unmatched energy for sure

Rohii

luiel

Alina

Thank you so much for reacting to them- they are so talented🌸hope you will see more of their content, because they are genuinely so special ☺️

blurrybini

Yaaay great reaction guys!! I had such a fun time, they really are amazing performers. If you want to check out more content from them i would recomend their documentary (its not that long and its divided into episodes, all on youtube) and their recent lollapalooza performance, since you said you were curious to see them perform 😄😄🩷🩷

Gabriela

YES GUYS REACT TO CORTIS LOLLAPALOOZA PERFORMANCE

Hi

Is it just me or does the choreography for ‘Fashion’ not sync with the song? 😭

p3ach

6:25 As a Canadian myself, I find it interesting whenever people say they're "half Canadian/American". Cause those are nationalities, not ethnicities. Why not just say they're half white/Caucasian 😅

Bri 🦔

Idk why I thought it was sand

bowie is tired

no way we’re starting to get carter aegyo reaction pics

Jo

Throw in that one “Just one day” practice where they couldn’t stop laughing😂😂

Totaa

Mic drop too

Totaa

React to the dance practice videos for the songs "Run BTS," "Baebsae," "MIC Drop," and "Go Go."

Elena Penovska

James the oldest 20 is the J hope of the group . You should watch coris doing BTS covers or just the tik toks between Cortis and BTS cause they support eachother a lot

Nina

You have to do Dance practices from SEVENTEEN

kimkimkoo

BTS, TXT, CORTIS MY TOP 3 !!!

kimkimkoo

Yes IU also has a dance practice videos

Snooze

It is and I think the editor messed up syncing the video but since I like the editor I'm gonna blame it on them.

Sasha (Yare Yare Daze)

McKay spotted the main dancer immediately. Not an easy task in that time limit.

House of Ellie

Nnn their tour/concerts are getting dragged….

2026-09-06 16:00 Thank you so much, geks! Now you know why we keep asking for dance practices for various groups. They are just too good and highly addictive. I can literally watch them all day long. Heck sometimes I do! And wow Cortis has swag for days.... They got that young hunger and explosive choatic energy. I love how they are having fun with it and don't take themselves too seriously. Their movements are smooth and precise but still feel laidback. This was such a joy to watch. I keep rewatching haha Dance practices are my absolute favorite. And I can't wait until you check out Stray Kids, ATEEZ, Seventeen, Enhypen, and TXT, EXO, Xikers choregraghy among several others! You all are in for a wild but epic ride!

I about died laughing when Carter said Martin was 6'8. He would be giant amost 7 foot. You guys always crack me up. 6'3, it's funny he's only an inch taller than my Dad. But he does have a massive presence I agree and it's cute seeing him tower over the members. He definitly stands out 😂

Betsy

James jaw could cut right through you so chiseled hahaha. Not to mention his dancing is so fluid and sharp. Color me impressed!

2026-09-06 16:00 Sorry this isn't Cortis relayed, but I'm excited for you all to check out Stray Kids dance practices in the future. I think you would love Domino, Easy, Maniac, God's Menu, Backdoor, and Thunderous choregraphy.

d ⁷

it was confusing when they announced their tour, but after couple stops no one seemed to be complaining bc cortis know how to get crowd hyped even with 2 eps

d ⁷

jack when is your audition to join cortis

Mandyyy

During the first dates there were some complaints because they repeated the same song several times like Fashion 5x or RedRed 4x

its me abeer

cortis are such Gen Z teenagers yall gotta watch their tiktoks they're pretty funny

Gabriela

YES YOU SHOULD REACT TO THEIR LIVE PERFORMANCES

G. A

Cortis tiktoks for next kpoptiktoks reactions

kri

This was so much fun to watch! MORE GEKPOP X CORTIS PLEASE

niiieres

cortis documentary on next weeks poll pls 🙏🏽

TY

Watching this at the airport going back home after watching CORTIS in SF and BTS in Toronto. Yes, CORTIS was amazing!! Worth the ~50 hr total flight (to and from and in between) 🫶

Tara Bowman

There Lola performance was insaine

Caroline

I am not that into Cortis (theyre so young😅) but i will always watch kpop dance practices! Its just insane how amazingly talented people are! And no bts did not start the dance practices and not the vlogs either. It was always a kpop thing! Yes, some labels should not do tours so early! but they do actually do this with a lot of the new kpop groups. The labels just want the money. Some groups learn a lot and grow as artist that way but its just a lot for any human to do so early.

loontan

PLEASE!!

jade LA

petition for yall to watch them at lolla

Beth Edwards

Cooking REDRED 1 would be so cool to see their reaction to how James handles choreography

hamzahahaha

YAYYY pls get more into their content too cause they ARE the funniest ever!!

Von Vvv

Day 7 requesting exo 2026 guide by aniri and/or their killing voice…

Sarah

I hope we get an early drop today☺️

Josie

Are they watching Fashion out of sync like we do with this video coz it feels like they are... kinda surprised their reaction to Fashion was relatively nonchalant since it has the most in-your-face intense movements but it explains if they were watching with the delayed audio bc dancing on the right beat makes the whole difference

d ⁷

frrr this kids just be doing some crazy stuff like how seonghyeon always injures the same finger all the time??

Loly

👀

Kaye

U need to watch their documentary first before any live performances/etc. they have as of now

Stilloctober

So i did go to one of the concerts of their tour (San Francisco day 1) and i thought it was amazing! The boys put on such a great show and the crowd was so loud and hype the whole time. At that time they had 14 songs and they performed most songs twice and some three times to make a 2 hour show which people were upset about but i feel like everyone that was there loved it! I loved getting to hear redred and go 3 times! And the crowd was just as excited the third time as if we were hearing it for the first time

Felix

You guys should do a video for Seventeen dance practices. The synchronization kings fr

alyce

!!!

Devrim

upp cooking redred is so cool to see

Devrim

if they're gonna do a live they should do lollapalooza for sure

NabiNoriNoodle

You missed the acai and tnt ones tho they are so good too

NabiNoriNoodle

I can’t wait for you to get into some of their vlog content or interviews

Gabriela

CORTIS LIVES PERFOMANCES AND MORE MVS PLS GEKS 🙏😭

Nellie

Fun dance practices video's 🕺

shweta masih

live performances are really nice

kc

MORE CORTIS!

Brie Reia (bribri0775)

I love how amazed you guys are with the in sync choreo and "timed jumps". 11:53 These are a variant of the "BigHit JUmp" all Bighit artists(BTS, TXT, Cortis) have perfected these types of same height level/ in sync jumps.

Kaye

Cortis next vid when

Stunflower

U guys gotta watch their tik toks hahahaha

val
