143∽'s debut live video from 2018/02/03 at Shinjuku ReNY!
143∽ are a new group produced by KOH, who used to produce SOUL↗︎UP, and before that ACATOCRO★ (and aotociro☆).
They perform some new songs and some songs from SOUL↗︎UP.
They also have a soundcloud at
https://soundcloud.com/user-488391473 but those are demo versions, not the full member line-up.
They have 6 members, Haru was from SOUL↗︎UP and ACATOCRO★, and Juri and Rinka were from CANDYIISTRIPE_NEO. One of the other members did something before, but not sure if idol or something else.
I think they sound really great!
