Its hard not to appreciate these girls talents... Once you get a chance to see them in behind the scenes of their come up and /or in interviews theyve done it will be hard for you not to fall in love with them as humans. They are pretty special.
IYKYK = "If You Know You Know". Funny that you mentioned a bootcamp that allowed them to debut with excellent songs from the start. XG was founded through an audition process which started in January of 2017 and was narrowed down to 21 candidates in 2018. These girls trained for 5 years to become XG. After a strict elimination process the 7 members remained to debut in March 2022. That's why they are already so polished from the start. The fantastic documentary series "Xtra Xtra" on XG's RU-vid channel (9 parts, starting with EP XX) gives lots of background how XG came to be. Perhaps you can react to it, too. But even if you only watch it by yourself, for more information about how the group came to be this series is highly recommended.
"It was like they were in a music group boot camp for five years before they released their first single" Well, let me tell you, you were spot on - they WERE in a music group boot camp before they released their first single, and it WAS 5 years! That's hilarious that you called out the only way they could have come out the gate like they did... crazy hard work. If you're ever curious about them coming up, there's a great docuseries on their youtube all about it.
Your favorite is Amy Janett Harvey, and goes by Harvey, and iykyk is If You Know, You Know, the other one you asked about is Cocona, she's a rapper and the youngest. Cocona did shave her head, in the woke up video, and has kept it buzzed since. the random short green haired dancers are just that. You should watch the dance practices and also the Move videos (the tapes and voxes are good too)
You like Harvey with her unique voice and the girl Shaved head is Cocona she's a good rapper. Did you watch Woke Up ? Cocona shaved her head in the video
So the person at the beginning of the video and in the hat during the second verse is Cocona she is the youngest member of the group and shaved her head in the Woke Up video.
