For September, there's actually no big group comeback, just some new group comeback or some new debut girl groups, the most famous one will be Red Velvet.
Red Velvet - Dumb Dumb
On September 3, 2015, Red Velvet announced their first full-length album The Red through their Instagram account. It is set to be released on September 9 with a total of ten tracks, including the single "Dumb Dumb".According to the group's members, "Dumb Dumb" tells the story of a teenage girl who becomes awkward whenever she falls in love. The music video for "Dumb Dumb" is set in a doll factory and was released on September 8, 2015. The album was received positively by critic.
Billboard's Jeff Benjamin called The Red "an impressive, solid debut album" and stated that it "indicates big things for the act that needs to follow in the footsteps of their beloved female label mates Girls' Generation and f(x)." The album topped both South Korea's Gaon Album Chart and Billboard's World Albums Chart.
It did better than the previous Ice Cream Cake comeback, now I can see Red Velvet has somewhat enter the 1st tier girl group level, but they are still new, need to work very hard in the future.....
As usual, I still divide comeback as cute style and sexy style or ballad comeback, and I will talk about the cute style comeback first.
DIA - Somehow
Besides Red Velvet, the most successful debut this month I would say DIA. (also known as Do It Amazing) is a 7 member kpop girl group debut under MBK Entertainment. They debuted on September 14, 2015 with the album Do It Amazing.
When DIA debut, they released 3 music videos in a row, also spent a lot of money filmed the title track in Hong Kong. It was considered as a very strong debut. The title song Somehow was quite catchy and also the dance as well. And I really like their outfit....
Unicore - Huk
Another new girl group also debut this month is Unicore, Unicore is a 5 member kpop girl group debut under ETN on September 3rd this year.
Their debut album are produced by Kim Jo Han, who's known for his R&B hits. The 5-member group are also be the first girl group ever to debut through a 'web-com' called 'I Am A Girl Group. And it's a brand new girl group as well.
VIVIDIVA - Service
VIVIDIVA is another 7 member kpop girl group debut under DN Entertainment this year. Unlike other new debut groups, DN Entertainment is trying an entirely new concept called performance idols. The performance idols focus solely on live performances, and the group VIVIDIVA is the first of its kind. The group will perform on small stages, where the fans and audience members will have more direct communication with the idols.
I think it is a very good approach, since there are way too many girl groups and competition nowadays, getting close to audience will let this group stand out with those too many girl groups.
Also for sexy style girl groups, there are few girl groups comeback this month as well.
Purfles - A Bad Thing
Purfles is a 3 member kpop girl group debut under Crescendo Music at 2014. Actually this group was already active since last year with their single 1,2,3. And this year they made a comeback at Sep, with the single "A Bad Thing".
This is a typical sexy style girl group, and their songs are actually not bad, and some are quite meaningful,
Global Icon - Doligo Doligo
Global Icon (also called GI) is a 5 member kpop girl group formed by Simtong Entertainment in 2013. he original line-up made their debut with the single "Beatles", released on April 3, 2013. The group originally debuted with a "boyish" concept, in which the members take on a more masculine attitude and style, opposed to feminine concepts many girl groups have. But as the group has gone through a change in the member lineup, they're taking on a more feminine concept compared to their original image since 2015 September comeback
Badkiz is a 5-member kpop girl group that debuted in 2014 under Zoo Entertainment. And they only had 4 members left now. Even though they debut almost a year until now, it seems to me they are still a new girl group for some reason.
The very last category, it's not either cute or sexy style girl gorup, BerryGood made a ballad comeback, so I made a separate list for that.
Berry Good - First Love
Berry Good is a 5 member kpop girl group debut under Asia Bridge Entertainment at May 2014 with the debut single "Love Letter". And they changed their members early this year, but still remains as a 5 member group. And they cameback with the ballad song "First Love".
It's a ballad single with a poetic melody and sad lyrics. It's a song that matches the fall season perfectly, and anyone who's experienced heartbreak will be able to resonate with the song
They are probably all good kids....
From here we can see except Red Velvet was under SM Entertainment, all other girl groups are from small labels for this month comeback, and a lot of agency I never heard of. But again, the problems with way too many girl groups in kpop nowadats which increases the competition and made them become famous much harder.....
