I admire Seohyun's professionalism, she had two wardrobe malfunctions that I didn't even notice until my second time watching this!

Seohyun's calm while having problem is really attract me

In my opinion, taetiseo is best vocal line in kpop. They all have solo album too. Their visual, vocal, dance are perfect combination

I love how seohyun tries her best in every single performance and always looks energetic and happy!

I personally like this better than Holler, they should've made a comeback with this instead (:

9 years ago I was there, watching this showcase live and for free, thanks to a kind security guard who let me, one friend and a Japanese mother and daughter enter for no specific reason. There's no way to express my gratitude for this human being, I hope he was blessed

Can I just say how enamored I am with Seohyun? Wow. Every single video of her, she just glows!!! She looks absolutely gorgeous in her outfit here! Well what am I even saying she looks beautiful in everything she wears because her body is perfect. The fact that she had a wardrobe malfunction that I didn't even notice until I saw the comments just made her 100 times greater. She totally nailed this performance! I mean come on. She's just amazing! She's lovely, classy, humble, intelligent, sweet, kind and funny! She sings and dances so well too! You go girl! :)

서현이 춤추면서 떨어진 모자 날리는거랑, 인이어(?)인지 뭔지 선 빠진거 집어넣는거 진짜 대멋지다... 프로야 프로 👍🏻👍🏻

I've always thought Adrenaline should've been their title song. Holler is good but this song is so much better imo.

Seohyun just prove how professional she is

Seohyun had wardrobe malfunction but a professional has nothing to worry about

와.... 서주현 페도라 떨어졌는데 당황 하나도 안하고 원래 퍼포먼스인 것처럼 하네 ...멋있다 프로페셔널.. 역시 서현 역시 소녀시대

Taeyeon lights me up with her smile and shyness, Tiffany smelts me with her eye-smile, and Sehyun knocks me down by her powerful shake! You guys has done marvels to us! Keep on going! Amazing performace!

Seohyun is stunning as always! I didn't even notice the malfunction, she is a pro!

Poor Seohyun she always have problems with her clothing or microphone.. but handled it like a pro! I love adrenaline more than holler^^

who's here after Chaewon, Yuri, Yujin from IZ*ONE covered this?

와 내가 귀찮아서 내가수 영상도 거의안보는사람인데 태티서 이건 진짜 대박이 왜 스엠은 이걸 타이틀로 쓰지 않은건가요 할라보다 이게 훨배좋은데!!!어쩌다본 아드레날린에 소시입덕할뻔 와 이건진짜 맨날들어도 안질린다

im such a big fan of girls' generation when i was a kid and now that im a wizone, izone's yujin, chaewon, and yuri covering this is such a win for me they slayed this so much!

진심 태티서 노래중 최애곡이다.. 물론 다른 노래들도 좋지만 이노래는 잊혀지지 않아

Seohyun is so professional.

여기서 개인적으로 제일 킬링은 티파니가 뉴뜬의 앱뽈 이러는 거..

I never noticed before how well Seohyun can dance o: ♥

Back then i was Sone for lyfe!! And now as a WIZ*ONE seeing Yujin Yuri Chaewon covered this make me extremely happy even ma bias Yuri cover my SNSD bias Taengoo part😭😭👏🏻👏🏻💕

Not at me searching this because minju mentioned that she would have wanted to do this unit stage with kkura and eunbi ^^

i miss TTS

I always love watching Seohyun dance during the chorus because she jumps so high. Lol I love seeing them have fun and enjoying what they do.

im here cause izone cover this and this truly amazing, as expected from legend GG

TTS live singing is always soooo goooddd... even better than the CD.. the choreography also really good.. seohyun split..

Watching this again in 2022 for a SNSD marathon cus of their comeback ❤️ Still one of my favorite SNSD songs of all time!

Seohyun is in pants, Tiffany is in stockings, but Kasper is the only who went ahead and touched Taeyeon's bare legs. Hahahaha! And I like that Taeyeon didn't hesitate to actually touch her partner too. Honestly, the dance feels more natural that way. Taeyeon's chemistry with Kasper on stage is seriously daebak! I'm even starting to think it can rival SehunxTaeyeon's chemistry.

Taeyeon is my bias but damn Tiffany killed it here!

Seohyun really shined with this choreography!

My second favorite song of the album. Both of the melody and the choreography are amazing.

I wish they have a mv for adrenaline. This song is my most favourite song in their album. Both choreograph and melody are fantastic. Love it!

I've been a SONE for a long time 'til now but then KZbin recommended this after I watched the cover song from IZ*One's Yujin, Chaewon and Yuri. ❤️❤️❤️❤️ So proud!

Thank you so much SM for releasing this 'Adrenaline' performance from the showcase. The choreo is so great and it will be so wasted if it's not broadcasted enough. I hope SM can post other songs from the showcase too.

I really like seohyuns part in adrenaline...oh and i like adrenaline so much not holler... Ps. Tiffany is really mature looking than taeyeon.

It's unbelievable how years past by. I remember whole comeback with the album and can't believe it's more than 6 years now 🤯

i'm here because samdaengz 😍😍 tts song is soooooo perfect

Seohyun so cool in this performance!

퍼포먼스와 3명 가창력, 다채로운 표정, 무대장앙력이 다 어울려진 무대를 모든사람들이 봐야하는데!!! 이 곡을 더블타이틀로하던가 방송에서 더많이 보여줬어야했는데... 너무 아쉽다. 명곡중명곡인데 ㅠㅠ 소속사가증말!!!!!😫😠

Seohyun really got a burst of adrenaline here haha ^^ It makes me happy to see her so excited and energetic ! Cute maknae !!

Beautiful Seohyun♡

Here after IZONE's YuYuChae cover on their concert ❤ Yujin and Taeyon's voice resembles in this song.

izones cover made me miss them so I came back

갓드레날린이라 불리는이유가 이영상에 다 있네..

It's nice to see people stopping here after Izone's cover. I love SNSD and TTS for life and people listening to them is very much appreciated. And also I am a Wizone too. So double treat.

Adrenaline is the song that you didn't realized how old this song was when you listend to. Damn!! i didn't realized until i watch izone cover to it then i watched because i miss snsd. Feel old again....

이곡은 진짜 언제들어도 안질리고 신나....

I'm here cause iz*one covered it, we love queens covering legends 💕

I am loving TTS's music, dancing, the Kpop fashion, and especially loving Tiffany's outfit (featuring the pleated tartan mini-skirt with the sheer black stay-up stockings and sheer black chiffon blouse)!🤩😍💗xx

They are always gorgeous,pretty,and nice.

Adrenaline’s choreography was so beautiful

I see thats why it is so familiar 😍 Iz*one and TiTaeSeo jjang ❤❤❤

Lol, no one asking y'all where you came from. Just appreciate this beautiful masterpiece.

She felt her hat falling off and immediately flung it away with style. RESPECT to the maknae! A true entertainer and artiste!

in my opinion this is better than Holler.

omg i fall in love into kasper & Taeyeon~~

my beautiful seohyunnn ♡ and lovely tippany and taengoo :")

BABY SEOHYUN ♡♡♡

Taeyeon and Tiffany are especially born for this. Seohyun is such a cutie too

who came here after watching taeyeon's solo part with kasper in why mv ( dance ver) ?? gosh they look so good together

So many comments same as with me = " i'm here because yuri,yujin chaewon iz*one cover this song"

Love that song Adrenaline of Girls Generation, They can sure move with heartbeats!😍😍😍😍😍❤❤❤❤❤

Seohyun is so HANDSOME~~HAAAAA

OH TTS WHY ARE YOU SO PERFECT😢😢😙

티파니의 apple 발음은 마치 딩초때 처음 들은 정석 apple발음 같다.

1:07 Seohyun.... YOU'RE A PRO

I love this choreography!

I'm completely in love with this song.

Love the choreo so much! Sm pleaseee share the other performances too!! Only u & stay live stage plsss! TIFFANYYY❤️❤️

Seohyuns so professional! She just casually rips her hat off her head at 1:07 like it wasnt even bothering her

I would love to see yonghwa,Nickhun, and baekhyun`s reaction hehe:D

I wish they would've performed 'EYES' during their comeback showcase... ;~; There's just something about that song I really like, especially that "For your eyes only~" part. They rocked this performance none the less and I am loving those outfits. I liked Tiff's the most tho.

love this performance

SNSD-TTS 'The best Trio' 🔥

Seohyun’s reaction of the problems are gold. How perfect she is

I love the dance choreography for Adrenaline :D it's so exciting and easy to follow(ish)

Awesome! Their performances are always so on point...Never lacking

Can people stop debating whether or not they're singing live or not. There are many times they've showcased their vocals: on radio shows, sketchbook, festival and concert performances, and other tv/music shows. Just because SM might've made them lipsync or use prerecorded audio does not mean they are bad singers. It just means that dancing and singing well at the same time is not their forte (this is usually the case for early idol girl groups, especially during the WonSoKa era). But does not being able to equally dance and sing a bad thing? Nope. They've shown their talents for 7+ years and as a fan, you need to have certain expectations, especially when it comes to SM....

me encanto la coreografia y el vestuario de Seohyun ♡

Yey! Thank you SM for uploading this! More please..... >.

The choreo and dancing in this is really superb!

I REALLY HAVE SO MANY MEMORIES WITH THIS 💔🍀👑

this song should be the title song more than holler love this song ♥

The feeling was so new to me seeing our Maknae Seohyun doing some interactions that long with the opposite sex after Yonghwa :3 Our innocent maknae has becoming sexier :)

Their hair looks perfect

love this song♥

I miss TTS 😢

thanks sm!

Woooow lo amo, es genial, el baile, la canción TODO!

My queens ❤️ This is so freaking perfect *.* and that maknae split never fails to wow me everytime I watch this performance

Wow!!! Sones, your girls are truly amazing! ELF and A+ here to support you all the way~! Holler!!!

Perfection

One of my favorite from TTS unit!🥺💓

ahhhh !!! the album is really amazing ! it's pity that holler was the title track !!! I LOVE ADRENALINE !!!! everything about it is PERFECT !!! SM how can you give us half of Seohyun split !!!!! She's shinning in this comeback !!!! TTS saranghae !!

Look like SM covered the audience reaction again, the whole video without any cheer and scream.....

OMG ADRENALINE FAV SONG IN THE HOLLER ALBUM

I lovee this song, I just knew about it yesterday

I have been waiting for the showcase version because I love this song!
