BTOB (비투비) - BACK DOOR (From Stray Kids) on Kingdom - Vocal Coach & Professional Singer Reaction 

What are your most favorite BtoB (I am so sorry for mispronunciation, I will make sure to get it correct next video) performances? Write them down, so I can check them out! :)

"THIS MAN DOES NOT LIKE SHIRT" got me LOL hahahaha thank you for reacting to btob again. Yes, those guys were a legend already. I can't quite imagine how proud Stray Kids was that BTOB covered their song. And they nail this performance! One of the best so far, in all of Kingdom performances. The other singer is LEE CHANGSUB. And he is an amazing singer, he was not feeling well during that time but he still was able to do a very great job. If you wish to hear more of BTOB as a group, you may check out Way Back Home, It's Okay, Remember That, Beautiful Pain and I'll Be Your Man (Stray Kids performed this song on Kingdom too). If you want with more on harmonizing and complimenting each vocals, you may check BTOB blue, their vocal sub-unit. I strongly suggest that you check To My Love, Stand By Me, When It Rains and a lot more. Looking forward for more btob reaction videos. All of them can sing and rap. Mind you, you'll be blown away 😁

Changbin's cry at the end: "Guys, THIS IS OUR SONG!" is _such_ a mood. As he said to Hongjoong when they were writing Playing with Paint, "I just love sharing music", and you can just tell how excited he is to see his seniors performing one of their compositions - and having such fun with it! 😁 The behind-the-scenes of the Mayfly (BTOB, Ateez and Stray Kids) performances are really enlightening; many of the members didn't know each other well, if at all, and you see them forming three incredibly close groups between them (you'll adore Bang Chan bonding with his new hyung Minhyuk (the blond rapper here), and Peniel (the other rapper) teasing his juniors into dropping their honorifics with him)...

Thay are vocal kings! You should react to their performance in Kingdom 'Show and Prove' or to some of their singles. I suggest you Missing You and I'll be your Man 💖 Thanks for your videos!

SKZ have called themselves Melody(BTOB fandom name) multiple times lol Han especially is a big fan and said Minhyuk(the guy who took his shirt off 😂) and another member who was not there are his favorite. Bang Chan and Peniel(rapper from Chicago) trained and lived together when at JYP. They were able to become really close again thanks to Kingdom 🥰

BTOB originally have 7 members, 1 member just left last Dec 2020. Only 4 joined Kingdom since the other 2 were in the military that time. They are vocally talented. You should definitely check more songs and live performances from them. They also have a vocal sub unit called BTOB BLUE. Love all their live performances especially their Immortal songs.

I believe Bangchan's bias in BTOB is Changsub (the other vocalist). I watched him ramble about how he loves him, how excited he is with their new song and how his most favorite song of his is At The End during his live streams. After Kingdom he also talked about how he was so happy because he got to hug Changsub during the finale. He's such a cutie. He was also very giddy and acted like a happy kid when Minhyuk complimented him. He is also a long time friend of Peniel, the bald rapper. He's from Chicago and don't read the translation/lyric of his rap here. You might also be flustered. Haha His rapping style is really westernized and he usually raps in English. He has a podcast called Get Real that is in English and he's a pretty cool guy. Unfortunately, Changsub was not really always present in the competition because during this performance, he was really sick. He wasn't able to stay for the rest of the taping. He was supposed to be part of the Love Poem performance but he can't. I believe he was okay to practice that time but they decided not to so that he could rest and he was also preparing for his musicals. 1 ongoing and 1 pre-production. I feel like Changsub's voice changes depending on what the song wants or needs? For this , he ought for it to be husky but a lot of time his voice is so clear and breathy. Sorry I don't know the terms. His clear voice was present during the Missing You performance. He mixed them up with Beautiful pain. I think you'll see the difference when you watch more especially with BTOB BLUE in Immortal Songs. He's called a vocal gangster because he makes whatever song he sing his. For Eunkwang, he's really powerful and he and Changsub mostly take the high pitch/register and the other two vocalists are baritones. He helped arrange Back Door. He's not just an idol but also a a Director in Cube Entertainment. He's a pretty big person but really2 humble. Yes, Minhyuk hates shirts and when wears a button up shirt, 3 buttons should be unbuttoned. He was an underground rapper before he was in BTOB. Very talented artist and very talented producer. They also performed Blue Moon in the show which he produced. He sang there because he's also a vocalist. All of them are but Minhyuk just chose to be a rapper because the loves rap. Blue Moon is a jazzy song which I think is very unique when it come to kpop and idol songs. Actually all the songs they performed, except Back Door, are froduced by BTOB themselves. The rappers write their own lines so that's why they all have different styles in the song but they really manage to integrate them together. Watch also Stray Kids' version of I'll Be Your Man by BTOB. watch their interaction while exchanging the songs because it really2 funny. I think this comment is too long... Hehe.. I'll be looking forward for the rest of their performnces... Thank you very much💙💙💙💙

Aaah you should watch their performance to finale (show and prove) they are so so so good and the song was amazing

I really like "Missing You", "When it Rains" & "Beautiful Pain" I hope you'll react to Stray Kids Cover "I'll Be Your Man" too And if you interested with unique vocal, you should check The Rose and Jung Dong Ha, they're underated.. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-B6qjTZIexjE.html Thanks for reaction, have a nice day 💙🤗

The other vocalist is Lee Changsub. He has one of the most unique and beautiful vocal tones in kpop industry. He was actually not feeling well during this performace. Some believed that they (changsub&eunkwang) were supposed to have a vocal break (just like in I'll be your Man) on this song (the part where they were facing each other and Eunkwang belts out the high notes) but were unable to perform it because he was not feeling well. Please react to their song "Finale: Our Concert" ... 💙

It is common for younger groups to cover songs fr older groups, but this was the other way around and that really means a lot to younger groups

I hope that when you get round to Stray Kids' cover of BTOB's "I'll Be Your Man," that you check out the original too. BTOB is a well respected artist in the industry. And you're like the second reactor I've heard say how it is a great honour when a senior covers a junior's song.

Beautiful pain the the song they performed for the 100 seconds performance during the first round. One of the rappers (minhyuk- he has blonde hair in this performance) was a part of the vocal line and did some amazing high notes along with eunkwang. It definitely worth looking at even though it’s only 100 seconds but by far one of my favourites

Omo, Are we getting I'll be your man (skz version) next? You should also check BtoB's introduction performance which they sang missing you. And also, it's pronounced as b-to-b because it stands for born to beat☺️

I'm a HUGE Melody (BTOB's fan) so I'm super excited about your new journey with them and can't wait to see it all! My fellow Melody are already suggesting content so I'll refrain from that, but if you're into for vocals for days and husky voices let me recommend the group A.C.E and their amazing covers (my personal fav is Empty Space)

Please please react to "To my love" and "under the sky" of Btob at Immortal song.

Ty for your reaction, for appreciating BTOB❤! The one who ripped out his shirt is Minhyuk, the other rapper is Peniel and then one who has husky voice is Changsub, btw-Eunkwang&Changsub are also active in musicals..Pls. React more on their Kingdom performances-Blue Moon and Show&prove. Their live performances is better than their MVs for me- as a whole group,my favorite songs are Only one for me, Stand by Me(BTOB BLUE) , Missing You & Beautiful pain ❤ Oh i forgot,their latest songs Outsider, Waiting for you&Dreamer

finally a BTOB reaction! i love your reaction 😊 I'm glad that now you have discovered 2/4 of BTOB's vocalist, can't wait for you to discover the other two. they're incredible as well... please react to their immortal songs performances "To My Love" and "Under The Sky" performed by BTOB Blue, it's their sub unit that consist of the vocal line

Please can you reaction to missing you in kingdom

The curly hair one named changsub.. He's not feeling well during that perf..

Please react to Kingdom version of Blue Moon. 🥺💙 There are more harmonies. You will love it.

Please consider reacting to BTOB vocal sub-unit's performance of To My Love on Immortal Songs, I think it is one of the best vocal performances of all time

So happy the maknaes are back now and can't wait for their comeback 🙌🏻

Hi, Thanks for checking out BtoB. Btob and Mamamoo are called Male and female version of each other. They both are great friends. Btob has 4 vocalist (although all of them can sing), you should check out their performances of 'To My Love' of all 4 vocalist on immortal song. That performance highlights each member beautifully. I would also like to recommend Btob Luv (Vocal Battle of Btob)!!! The other Vocalist here other than Eunkwang i.e. Changsub was sick during this performance. And you're so right about Minhyuk not liking Shirts, have you seen his recent photoshoot, you can check it on his ig or Twitter. Peniel is from Chicago, he's fluent in English and yes his flow is so fun and good. There are 3 other members who didn't participated in kingdom. They're self made group, I hope you could check them out more in future~ And you also need to check out how they're when not on stage..... it's CHAOS.

Changsub is the member with husky and rich voice at the beginning. He's the lead vocal of the group. He was present in some of the stages as he was performing at Marie Antoinette musical too at that time when the show was aired.

Thank you very much for your reaction! I love how you pointed out the techniques they used for their voices. If it’s not much of a hassle, can you please react to BTOB BLUE (vocal line sub-unit) performances through the years. I have no educational background on music but I can say that I have an ear of a musician since I come from a family of musicians, but still, I think you have a better ear than me 😅 So I would like to know how each vocalist’s voice changed over the years, how they changed their singing techniques, etc. 2014: MNET show: “For Thousand Days” (cover) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lTcNqqiuOps.html 2015: Born TO Beat Time 2015 concert: “I’ll Be Here” (original song) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_FrgwAUjFHQ.html 2016: Immortal Songs: “To My Love” (cover) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-a6DNkLvHxZ8.html 2017: Immortal Song: “Under The Sky” (cover) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xSNiCWEo-M0.html 2018: Sugar Man: “Cold” (cover) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-f71MCbigBJc.html 2018 was the start of BTOB’s military hiatus and 2 vocalists served together between 2018-2020 while the other 2 vocalists served between 2020-2021 so there hasnt been another performance as the vocal line sub unit 😅 Thank you very much 💙 I hope you will fall in love with BTOB as much as I do 🥰

I'd love it if you could also react to Blue Moon on kingdom also! And also would love it if you would react to their normal songs with all members, they do mostly ballads and I'd like to know your opinion on it

Wow, thank you for reacting to BTOB. They are one of the best vocals in K-POP. You may check BTOB-Blue's immortal songs and sugarman performaces. For the whole group I recommend I'll Be Your Man, Someday, Love Drunk, Finale: Our Concert and The Feeling.

Beautiful pain for OT7, Alone for Btob 4u and Stand by Me by Btob Blue. As for the rappers, goodnight by Huta (Minhyuk) and She's gone by Ilhoon. These are favs. Great songs, great people. Edit: And Blue Moon for the Jazz Flair lol. Big jazz fan here🤣 Edit 2: And all of their solos tbh. You just cant pick🤣 Edit 3: Wait till you see Hyunsik lol i can't stop. Theres too many stuff to talk about Btob🤣🤣🤣

Stray Kids also did something like this in kingdom too they did BTOB’s “I’ll be your man” and omg they killed it

plz react to stray kids kingdom performance -i'll be your man

So happy to see people reacting btob 😁 you should check btob blue (vocal unit that has eunkwang changsub sungjae and hyunsik) two vocalist here and the other two is from full btob 'immortal songs 2' and please react to more lives that has all the 7 members :D

Thank you very much for reacting to btob, if you want to appreciate his vocals more, I recommend his trilogy of ballads: way back home, it's okay and remember that. It would be great if you react to them in their live performances, many say they are better live than their studio version

Vocal King

Btob nickname in Korea actually is ballad-dol. They have a very strong vocal line consist of 4 members out of 6 (used to be 7 members). But surprisingly, their second nickname is beagle-dol because they also well-known as one of funniest kpop group, which makes them very unique because of their reversal charm. Since you kinda into vocal, here are some of their songs with strong vocal Show and Prove (Kingdom final, composed by member Minhyuk) When It Rains (vocal line, composed by member Hyunsik) Beautiful Pain (composed by Hyunsik) I'll Be Your Man (composed by Hyunsik) Please/Climax (not a title track, composed by Minhyuk) Someday (not a title track, composed by Hyunsik) Also there are 2 version of Kingdom performance video. One is direct cut from the broadcast (with reaction from other groups just like what u watched here), and the other one have Full Version (풀버전) in the title (without reaction). Just telling you in case u want to watch the clean ver. Anyway, thank you for reacting! ^^

Stray kids choose BtoB themselves for remake one of their songs. BtoB debuted in 2012 as a 7 members group, sadly the main rapper left the group at the end of 2020, the other two members was on military service during kingdom, by now all the 6 members have ended their militar service. Seo Eunkwang 1990 Main vocal and leader. Lee Minhyuk 1990 lead rapper, unofficial main dancer 😅 shirtless, composer, producer, lyrics Lee Changsub 1991 lead vocal tenor (the other singer in this video) Lyrics Im Hyunsik 1992 sub vocal composer producer baritone. Peniel 1993 rapper born in Chicago, lyrics Jung Ilhoon 1994 main rapper left the group, amazing rapper composer producer, lyrics. Yook Seungjae 1995 sub vocal baritone, starting in produce too. This was the subunit active at the time BtoB 4u on kingdom I recommend their stage song Missing you, composed for Member Hyunsik and actual ATEEZ producer EDEN.

Every member in BTOB is so talented. You need to see all vocalist have their unique and strength. And also very strong rap line 💙 thank you for react to btob. And looking foward for more 🙏🏼

These 4 guys are called BTOB 4U and did well in Kingdom despite their age and lack in number. The other 3 members were in the military that time. But do please check out all of their amazing performances in Kingdom before you react to their other stuff. Their Kingdom perfs were unique and creative and had that distinct BTOB style. They started the 100 secs Intro Stage with BEAUTIFUL PAIN. Then the MISSING YOU theatre version. Then this BACK DOOR. Then the amazing BLUE MOON cinema version and their grand ending song FINALE:SHOW and PROVE. You'll love that they can do all kinds of concept and are very versatile. Please do these first then their Immortal Songs next. 😊 Thank you.

for goodness sake, react to BTOB's I'll Be Your Man, but the live, not MV LOL (anything live from them is awesome)

BTOB - Missing you is such a great song!

Always love your reactions! BTOB is such a talented group and Stray Kids look up to them so much. The two groups have grown really close during Kingdom, it's the sweetest thing to see. I'll Be Your Man is such a legendary BTOB song, SKZ has covered it on Kingdom too so it'd be super cool if you checked out both versions! All of BTOB's performances on Kingdom were amazing: Beautiful Pain, Missing You, Blue Moon, and Finale (Show and Prove). Their latest comeback was Outsider and it was so good, the whole album was actually! Just wanted to thank you so much for your videos, they're super fun to watch and I learn a lot from them! Looking forward to more :)

BtoB stage is lit even without complete members. Im glad they join kingdom.. thank you for your reaction 💙

Ohhh!! U got it on target! All members have their own color but it makes btob’s color. The funny thing is you only saw 4 out of the 7 members (2 members was on mandatory military service and 1 had to exit the group, he’ll be back mark my word!) anyways hehehe plssss check them out!!!

I can't wait for you to dive into BTOB. I'm a Melody-Moomoo and I always believed that BTOB is the male counterpart of Mamamoo :)

Please react to I’ll be your man ( from BTOB ) on kingdom

Changsub's voice my favv Eunkwang too dangg

Thank you for the great review! Please continue discovering BTOB's talents. Looking forward for more BTOB contents.

What about you watched their other performance in kingdom? Missing you, Blue Moon, and Show and Prove~ You can write "full" everytime you searched for it, so there won't be any reaction in the middle of the performance. There are 4 vocals in BTOB, and 3 rappers in this group. The other singer in that performance is Changsub. The other vocalists are Sungjae and Hyunsik, both are baritone. You can react to their MV as well. Can't wait for your next reactions~

Seo Eun Kwang and Lee Chang Sub (vocalists on this perf) were musical actors as well. Please react to Someday, I'll be Your Man (Stray Kids perfomed this here in Kingdom), It's Okay, Way Back Home.. 😊💙

Thank you for the reaction😍 Can you react to stray kids i'll be your man performance😊

It is quite rare to find someone who react genuinely to Peniel's rap, but here you are! Love it that you notice his distinct style (not to mention his buff as well haha). Originally, BTOB has 3 rappers, each with their own signature style. Minhyuk, the blond shirt-hater one, raps hard and sexy. Peniel is in charge of english rap and, like you said, brings more western feel to his rap. There were times where his rap went almost too melodious that he sounds like singing, but not exactly. I'd say his is a melodic rap. And the last rapper, the former member of BTOB, is Jung Ilhoon. Oh boy, he brought so much color to BTOB rap and also BTOB music because he composed several of their songs. His style is lazy rapping. You should listen to their song to understand what lazy rapping is all about. Dear Katriinka, you are on the right way of being a hard core Melody! Congratulations 😁

blue moon plz :)

watch please other btob perfomances from kingdom, they are breathtaking

Pls react to straykids I'll be your man

You should check "i'll be your man" from btob

This performance killed me. Seeing Eunkwang with fake tattoos and dressed like a rocker, Minhyuk just existing…I died. Keep in mind two members aren’t on Kingdom with them because they were in the military. They are out now, and I recommend you check out older BTOB songs. To see more of their voices, I’d watch the 90second intro performance and the Show and Prove performance.

The members of the BTOB group sing well, hit high notes. Wonderful But the song "Black door" itself, performed by them, turned out to be not at all interesting

I like how you react to Love Poem and now to BTOB's Backdoor. You can check out their I'll be your Man MV and live and Missing you with the full group. The members who performed in Kingdom BTOB4U released Show your love and Outsider. From Kingdom you can check Finale: Show and Prove . I look forward to more reactions. Thank you🙏

Well, I'm asexual but strongly questioning seeing shirtless Minhyuk saying: "You wanna come in?" so... But I'm sure other guys told him he have to do it like they did in previous round when they made him dance with a sword like a fight choreo because it'd look cool 😂 But shirtless is like a Kingdom tradition going as far as Road to Kingdom.

I can't wait for you to discover more of BTOB... you'll love them for sure! :) thank you for your reaction :)

You really need to check btob more, you will love them, I promise

If you want react the Kingdom's performance, I recommended choose the video with "Full Ver", Bcs there's no other group reaction in there

You really need to react to BTOB's performances in Immortal Song. Thanks for the reaction😁

Changsub (The other singer) was actually really sick that day like going thru a fever and stuff... he couldn´t even participate in the interviews for a few episodes but he still tried his best to perform. That´s why he sounds a little more husky than usual! He is actually known for his angelic and UNIQUE AF tone and therefore almost always starts out their songs! You should react to their "Finale: Show and Prove" performance on Kingdom! He is healthy there and kills everyone with his lower register and falsetto LOL MInhyuk (guy who hates his shirts 😂) is just rude LOL alwys walking around shirtless while spitting some fire causing Melodys to die internally and externally simultaneously.... Did I mention that he is rude 😂 But he is actually the most sweet an caring for the fans. never turns back a request and communicates a looot with Melodies. Sweetest of all! Peniel (the other buff rapper) is actually American! so yeah he is influenced by western music a lot! He has a unique tone even as a rapper and it just sounds sooo good! He is very caring and loves (and is loved by) his members a lot, always taking care of little things for them! Probably the most chill member cause... he a robot LOL! But sometimes... he just... turns weird as well... like all of them!

more BTOB reaction plsssssssssssss

You should check btob Blue Moon kingdom performance too

Thank you for reacting to BTOB! BTOB are originally 7 members. 4 vocalists and 3 rappers. Some were in military when they filmed Kingdom. Please react to all the performance in Kingdom, since you can get to know these 4 first, maybe it's easier.

Please react to stray Kids I’ll be your man (for btob) on kingdom

OH GOSH!!!!!!BTOB!!!!!!!!!!!!!!!!!!!!! HOLYMOLY!!!!!!!!!!!!!!!!!!!!!

now you gotta react to skz singing I'll be your man, by BtoB obv

Thank you for reacting BTOB. finally.. thank you soo much..BEAUTIFUL PAIN,MISSING YOU,STAND BY ME,UNDER THE SKY, TO MY LOVE,MOVIE,ITS OKEY but I love all of their songs.. Looking forward for more BTOB reaction.. thank you soo much .I have soo much fun watching your reaction video..😊

Thank you for reacting to BTOB 💙pls react to their songs, missing you and beautiful pain

been waiting for this everyday since you reacted to love poem💙 can't wait for you to discover more of BTOB💙 If it's okay with you can you please also react to Lee Changsub's The Reason I want To Die cover? Thank you so much💙

One of my favourite Btob song is Climax. But there's no live version tho. Just a few fancam from their fan meeting and a solo cover from Eunkwang on ig live. That is vocal heavy song. And seeing how you love husky voices, Hyunsik has pretty husky voice😍.

Thnk u for reacting btob.. We luv this group so much.. 😍 💙

Check out the lyric video for Finale(Show and Prove) and live version as well!

More BTOB please~~

i really enjoyed your reaction! hope you check more BTOB's songs like missing you, I'll be your man, it's okay, way back home, remember that, someday, etc. i also prefer their live performances cuz BTOB always sounds better live 😊💙

BTOB - FINALE (Show & Prove).... their final performance in Kingdom! Is a song that i can't get out of my head and would really like to see you reacting to it!

i would recommend BTOB Lee Changsbub cover of amazarashi. It touches u even if u don't understand what he's singing

I can't wait for your BTOB reaction video.😆 I've subscribed 🤓😻💞

Can't wait for your another BTOB reaction. ❤

I'd like to list some of their songs but a lot have listed them. So I'll just sit here and wait for any BTOB reactions 🤣💙

I'm telling you react to any of BTOB live performance and you'll amazed by these vocal kings🔥💙

I highly recommend this video: When It Rains - BTOB Vocal Line (pls skip to 1:27) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TBmb6Zt8R9s.html

Thank you🥺💙

I'm looking forward to more Kingdom reactions. I love the full versions because the song is uninterrupted, but I also love seeing the other performers reactions. I.N. looked like he was going to die of happiness during BtoB's introductory performance and ATEEZ's Seonghwa was moved to tears during BtoB's performance of Missing You. It's so heart-warming to see how much they admire their sunbaenims. Maybe the full version could be your first pass and the longer version your second (or the other way around).

OHH I LOVE BTOB!

Thank you!

Idk what what wind blew that i'm here digging more on kingdom performances out of the blue(its 3 am here) and found your reaction video and honestly enjoyed rewatching it with you. Also u should check out eunkwang's(btob) other solo performances. Trust me u will never be disappointed in his singing. One of that i really recommend would be his performance('peppermint candy') with another participant in a show 'All IN'(kind of a singing betting show, i didn't watch the whole show tho😅). And being not a fan of trot songs he is the reason why i'm so obsessed with his trot song performances with changsub(also btob member). If you want u should also check out btob as a whole group's songs(both mv and stage show). btob songs are a seperate genre. Istg they are so damn talented but kind of underrated. Its such a shame for those who got to know them only after kingdom. But as they say, better late than never.

THIS MAN DOES NOT LIKE SHIRT, yes that's how we can resume Minhyukie's personality

LOVE UR VIDEOS & REACTIONS

Please react to GOT the beat “Step back”

Vocal king

I really love your videos BtoB are one of my favorite boy groups specially when it comes to their vocals 😩i live. also btob stands for born to beat

Pls react to BTOBs performances on Immortal Songs ‘Under the Sky’ and ‘To my Love’ you will absolutely love them💯

Now that the other 2 members of BTOB are back from the army. They are complete and you are in for a treat!!Please do a video when they do a comeback!!
