Thanks for posting those!
Damnnnn. . . after watching those and other vids (i did a little digging after XD). . . damn. If they were still around, they could've been probably be one of the strongest girl group in terms of live performance (dance and vocals) with all due respect to other gg. They would have probably set the bar higher for all girl groups (maybe even change the current kpop gg "meta"). They have cleanest dance covers i have seen from a girl group (they did covers of boy group songs too, which we all know are stronger and harder to pull off.) Well synchronised and well executed, I'd put them at the top. If you feel a group you know can dance better, pls post vids of them and tag me. I'll gladly watch : )
PS: This entire post might be biased and not as objective as I wanted. (I'm not a dancer, so i have no idea how to be objective lol)
PPS: I just learned about them and want to stan them now but they disbanded. . . Talent alone is not enough to succeed in kpop i guess. fml
