Great reaction - and at the risk of repeating info you already have - the Kami Band that night were Leda Cygnus (blue guitar), Takayoshi Ohmura (gold guitar), BOH (6 string bass) and Hideki Aoyama (drums).

There can't be many vocalists who would fancy their chances following in instrumental intro like that (as you are aware it is its own thing with its own title 'Mischiefs of the Metal Gods'), but 16 year old Su just rises up from the depths of "below stage" on her little platform as if she was summoned by the Kami ... and she takes over the stage, standing high up, all lights on her, the Kami slowly spinning around below her.

'Rondo of Nightmare' is possibly the darkest of their songs lyrically, Su is caught in a recurring nightmare running through the dark from something she can't see.  In the part with her looking like she was almost suspended in mid air she is hiding in or by a fountain, but whatever has been chasing her is still coming closer and, accepting there is no escape, she asks that if she is to die won't it at least show itself to her.

SuMetal really flexing her vocal muscles on this one 🦊🤘

The Kami Band members all have their own projects outside of Babymetal. Some more rock oriented, some more jazz oriented, and others that are more progressive. Some of those projects have several Kami members in them as well.

Queen SU and her Kamis shows the world how it's done! 🤘🦊🤘

Who can believe she was just 16 in this video?

I love Boh’s enthusiasm when he plays bass. You can always tell he’s just out there having fun.

BABYMETAL🔥🤘🦊🤘🔥🤘

Su-Metal has 4 solo songs. Besides this song, there is the most popular Akatsuki, Amore, where you can hear the superb performance of the Kami Band, and the moving rock ballad No Rain No Rainbow.All are wonderful songs.

Has he heard Akatsuki yet? :D

The hill of wisteria is song by Yakayoshi Ohmura one of the guitarrist and the whole band is on it

Lyrics Overview:-
"Rondo Of Nightmare (悪夢の輪舞曲; Akumu No Rondo)"

欠けた月が　照らし出した
陰りの中　はびこる狂気
笑い声　響き渡り
牙をむいて　目を光らせている
逃げられない

ゆらゆら　揺らめく
心に見え隠れ
悪夢の輪舞曲が　繰り返されている
目覚めの光は
遥かかなた　見えなくなり
ただ　走り抜ける
闇の中を

森の中　泉の中
息を殺し　身を潜めても
迫り来る　すぐ近くに
淀んだ声　終わらない夜
嗚呼...

もう　ここから　出られないのなら
貴方の　姿を　見せてはくれないか

ゆらゆら　揺らめく
心に見え隠れ
悪夢の輪舞曲が　繰り返されている
目覚めの光は
遥かかなた　見えなくなる
ただ　堕ちていくの
闇の中へ

[English:]

The waning moon has lit up
the insanity rampant in the shade
The laughter resounds around
It bares its fangs and its eyes gleam
I can’t escape from it

It flickers slowly
appearing and disappearing in my mind
A nightmare rondo is being repeated
The awakening light
is gone far away out of my sight
I can do nothing but run
through the darkness

In the woods, in the fountain
I hide myself holding my breath
but it’s still coming closer to me
A stagnant voice. An endless night
Ah…

If I can no longer get out of here
won’t you show me your figure?

It flickers slowly
appearing and disappearing in my mind
A nightmare rondo is being repeated
The awakening light
is gone far away out of my sight
I can do nothing but fall
into the darkness

Kitsune Up 🦊🦊🦊🤘🤘🤘🇯🇵🇸🇬#notacult.

Great reaction, thanks!
This was just the second time they performed it live (the first one was just the previous night at the same venue) and Su-metal, being 16 at the time,  was standing by herself on a relatively small and high platform, without any safety and probably not being able so see a thing due the spotlight. And she still performed like THIS. Wonder why she's called the Queen?
The "rondo" in the name refers to the musical refrain form. The typical feature of any rondo is the return to the main theme after each digression giving the song a dark feeling of moving in circles without any possible way out. One of the best known rondos is Beethoven's "Für Elise".
See you next time!

Great stuff as always. Most Babymetal are like that. My favorite song is whichever one I'm listening to at the time. I tried several times to make a 'top 10' or even 20. I can't do it.

Suzuka Nakamoto was born to be a Queen. And she's not even 26 yet. Can you imagine this much power when she turn 30? 🔥🔥🔥

Thanks again from Japan 有難う💛。As other viewers commented below, each member of Kami Band is working on his own project.  If you want to see the bassist BOH's usual performance (as a fusion musician), you can find a good and recent video with key words - kari band u/yeah!!
"Rondo" is a musical form with a recurring leading theme. I can't tell how many times I have viewed this video. It is literally a rondo of happy dream for me. Kamis' super solos were excellent enough as a main event in the show, but once the 16-year-old Queen (as of 2014) emerged from the underground, she colored everything differently with her penetrating voice then turned Kami Band's plays into a ritual to summon her.

I prefer this solo section a lot over the one you have seen in CMIYC. The background music is more melodic, and the same goes for every individual solo part as well. I'm in love with Ohmura's bends and overall phrasing in this and in general. As for the actual song, it's one of my absolute favourites. The melody of the chorus is pretty damn perfect with its haunting dark beauty. The atmosphere of the whole song is very intense and fits the lyrics perfectly.

BOH raises his arms as to say Your Welcome

Great reaction and yes, that was from the same show as "Catch me if you can" (Budokan Black Night). Of course, Boh steals the show (probably because you don't see that many bass solos) but each member of the Kami band is insanely skilled. All of them have their own project, but the most known one is probably the Kari band. Some (if not all) of them have released albums or singles and played with their own projects their own shows (or part of a larger show).
Solos in order: Leda Cydnus (blue guitar), Takayoshi Ohmura (golden guitar), Boh (bass), and Aoyama Hideki (Drums).
This song is probably the darkest in Babymetals discography, a song about Su being trapped in a repeated nightmare, being chased but some invisible entity, fleeing to a well or fountain and begging it to reveal itself before she dies. The Rondo term in the song title has two meanings, one being a musical term for a repeated theme and two the nightmare being repeated over and over again. Can you imagine that this was only the second time this song was performed (it had its premiere the night before)? Su fearlessly singing and dancing on that small platform without any safety net at her age (16!) is just unbelievable. Fantastic song and performance from everyone! looking forward to your next reaction!

This was the first concert where the Kami band played the whole concert live. On previous concerts, the mime band Babybones, would play the first half, and there Kami band would play the other half or the encore. The one constant member that has been there from the beginning is Leda Cygnus, who is also a member of the band Galneryus (I'll add some links at the end). Takayoshi Ohmura, the one with the pink guitar, is the second one to be there the longest. He has his own band and has played with Marty Friedman in his band. Third would be Mikio Fujioka, an actual music professor at University, who was a teacher to Takayoshi. This is Boh's third concert and has become pretty much the permanent bass player for the Kami. Although he, Mikio and another BABYMETAL drummer named Yuya Maeta, formed the Kari band. A metal jazz fusion instrumental group. This is all pre 2019. As after Mikio's death, his position was taken once again by Leda Cygnus and new addition ISAO.
In 2019 the Western Kami were introduced. Which consisted of GALACTIC EMPIRE guitarist Chris Kelly, CJ Masciantonio, Clint Tustin on bass, and Anthony Barone on drums. They played the US and European legs of their 2019 Metal Galaxy tour.
LEDA also plays in other bands liked Deluhi, and Undivide. I could pick which video to give you😂, so here one of my favorites.

Here's one of Takayoshi Ohmura, who released a new album about 6 months ago. https://youtu.be/FuW6IsR3ybc
Here is Mikio Fujioka, Boh, and Yuya Maeta in the Kari band.

And as a special bonus, here are the Kami band members playing a song they wrote together while in Babymetal, and actually got to play it once in a BABYMETAL concert. This song is not a BABYMETAL song. This is Takayoshi , Mikio, Boh, and Hideki playing The Hills Of Wisteria played during a Takayoshi Ohmura concert.

Epic performance!!! 🔥🔥🔥🤘🦊🤘
