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

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!

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

Seohyun's calm while having problem is really attract me

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! :)

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!

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

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!

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

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

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

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

Seohyun just prove how professional she is

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

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

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😭😭👏🏻👏🏻💕

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

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

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

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

여기서 개인적으로 제일 킬링은 티파니가 뉴뜬의 앱뽈 이러는 거..

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.

Seohyun really shined with this choreography!

Seohyun is so professional.

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

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

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!

TTS must comeback now.

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.

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!

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

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

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

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

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 🤯

Taeyeon is my bias but damn Tiffany killed it here!

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

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.

Seohyun so cool in this performance!

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

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

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

Beautiful Seohyun♡

Yes Seohyun! Shake it baby, shake it!

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

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

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

TTS is always the best..but I like my bias the most..Seohyun~~~

i miss TTS

I just loved how Seohyun thew her hat. It was a wardrobe malfunction, but it wasn't even obvious. That was awesome, and so were their outfits, and so was this song, and so was this dance. ;u; I personally like this more that Holler.

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

Seohyun you queen covering up those malfunctions so well ❤️ also did anyone else notice that while Seohyun had changed out of her heels from Cater 2 u and Holler to boots but Taeyeon stayed in thin heels? All three of them are honestly queens. SONE forever ❤️ ❤️

They are always gorgeous,pretty,and nice.

taeyeon's smile is so bright and genuine here. facial expression wise she steals the show here

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....

This song should have been the title track! There is so much more choreography and i like the song a lot better than holler. Best song on the album *thumbs up*

이곡은 진짜 언제들어도 안질리고 신나....

SNSD-TTS 'The best Trio' 🔥

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....

omg i fall in love into kasper & Taeyeon~~

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

Adrenaline’s choreography was so beautiful

Seohyun has always been charming, but even more so in the performances for this album. So breathtakingly beautiful and bright. Love her.

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 !!

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

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

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

the fact iz*one performed an album track, snsd's discography is pure gold. listen to its demo by velvet angels

I'm completely in love with this song.

I love this song and performance but this needs the bright and colorful outfits!

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

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

Seohyun is so HANDSOME~~HAAAAA

They just charmed my socks off with that performance!! Totally should've been their promo song

wowww!!!What a performance!!! Taeyeon 😘😘😘 TTS 💕💕💕

for those who is still wondering it's live or not, listen at 0:44 and 1:20 at 0:44 : "oh wait! Neoman chaja danyeo" at "danyeo" part, Taeng slipped the note a little bit. Yes, it's because of her moves. It sounds different with the studio version. at 1:20 : "neol dulleossan sesangi hwieojyeo" at "hwieojyeo" part, we can hear Tiffany's breath at "hwi". It's like she's blowing the mic. Which we can't find at studio version. Yes, it's live. And remastered.. :)

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

OMYGHAAAD SEOHYUN EVERYTIMEEEE EVERYTIMEEEEEEE. You give that look tells 'IM SOOO HOT LOOK AT ME' EVEN COSTUME MALFUNCTION CAN'T STOP YOU OMYGOOOOOOOOOOOOOD

me encanto la coreografia y el vestuario de Seohyun ♡

이 노래는 들을 때마다 개설렌다

The way Seohyun threw off her hat is so cool.

we are always one...we are always one...we are always one...we are always one...

OH TTS WHY ARE YOU SO PERFECT😢😢😙

Bless SM for releasing this performance.

BABY SEOHYUN ♡♡♡

I love this choreography!

I don't care if they're lip synced or not, I love this song on this album so much

omg this song is so tiring and look how stable they sing and sync their every single dance moves. their insane training pays off. perfect as usual!!

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

Seohyn sooo incredible

I could hear their vocal clearly, and the music/audio was editted by SM and change it with audio studio ver. this is awesome !!!!! Thanks SM : )

This might be my favorite performance by TTS, Girl's generation in general. My favorite part was when Seoyhun was shaking it in the beginning, that took me by suprise.

For audience in here , actually TTS are singing live in this comeback , but SM recorded this video and replace the song .Hence , we all can hear they arent singing live , actually they are , SM does something on it

OMG ADRENALINE FAV SONG IN THE HOLLER ALBUM

Their hair looks perfect

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.

I lovee this song, I just knew about it yesterday

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