What girl group writes and composes their own music and also debuted a single and music video on the same day?
Pristin Pristin (Hangul: 프리스틴 ; stylized as PRISTIN and formerly known as Pledis Girlz) is a South Korean girl group formed by Pledis Entertainment in 2016. The group is composed of ten members: Nayoung, Roa, Yuha, Eunwoo, Rena, Kyulkyung, Yehana, Sungyeon, Xiyeon and Kyla. Most of them appeared on the television show "Produce 101" and, as the prize for becoming two of the top contestants, Nayoung and Kyulkyung went on to debut as part of the project girl group I.O.I, before reuniting with the other members to debut as Pristin on March 21, 2017, with the first mini album "Hi! Pristin". Like their labelmate group Seventeen, Pristin is known for writing and composing their own music.
...I R'n'B ...I R'n'b (eng. "...And R'n'B") is the debut single by adult model and singer Ewa Sonnet. The single was released in mid-2005 and became a hit, thanks in part to a popular music video by Swedish director Deevo von Brahust known, among other things, for directing videos for international stars such as AC/DC, Roxette and Sabrina. The video's screenplay was written by Bo Martin. The single was produced by Robert Janson for the Aurolac Studio and mixed by Prince Charles Alexander at Quad Studios NYC with mastering by Sterling Sound Studio NYC (Tom Coyne). The accompanying video's main focus is the artist herself playing a lookalike coupled with a catchy beat.
