Morimo? Are you trying to say MomoClo?
Anyway insane energy, great, always surprising singles, insane energy, some real joy and talent in performing, unlike many idol groups, and insane energy for their epic spectacle live shows.
I mean even setting aside the fact that both groups love the spectacle of dressing up MomoClo have collab'd with several JP rock and indie legends before and foreign artists as well (go team) so I wouldn't say it's too surprising, the only question is if KISS really have anything to offer anymore.
my guess would probably be "no" but we'll see. but yeah to kind of echo what you said, Momoclo have made it big on the back of
- being fun
- being more talented than the average idol group
- being unpredictable and awesome musically
- not being overtly sexual or submissive, which has led to them also having a huge female audience as well
they came along when something like them was sorely needed in the industry. as a side benefit, they've kind of allowed a wave of similarly-inspired groups to pop up in their wake. it's a nice change from the "I can't tell these girls apart" and "buy our gravure books!" method of idoling.
On another note entirely, that Ten Tenko song is great. I love her so much, glad to see she's kicking ass as a solo artist. Kind of patiently waiting to see what the rest of BiS are doing with their own new projects. Pour Lui's band isn't doing anything for me. Saki's group (Pla2Me) released a solid single. Nozomi and Uika (Billie Idle) haven't put anything out yet.
edit: catching up on the rest of the thread, I'm happy to see both Suiyobi no Campanella and Oomori Seiko getting some love. Can't wait for that new Oomori album
