This was SNSD, circa 2012. SNSD So Nyeo Shi Dae, “Girls’ Generation” is a K-pop group assembled over the last eight years. The first member, sixth in line, in the dress the color of dried ketchup, is Jessica Jung, who had signed her first contract with S. M. Entertainment in 2000 when she was eleven; S. M. named her as the first member of SNSD in 2007. And seven years later, Jung was the first member of SNSD to be sacked, apparently for having too many outside interests conflicting with group activities, starting with her appearance in a Korean production of the musical Legally Blonde. (How blonde is she? Not very, I suspect.)
I have no idea what that black box is for, unless it’s to obscure a brand name that didn’t pony up for promotional money.
There were also a number of non-SNSD singles, including this song from the TV series Dating Agency: Cyrano, which ran for 16 episodes in 2013:
Incidentally, Jessica Jung was born in San Francisco, and didn’t actually relocate to South Korea until 2000, when she and younger sister Krystal, then on a family vacation, were offered tryouts by the S. M. conglomerate. Krystal, now 20, is a member of singing group f(x), which was the first K-pop act to appear at SXSW.
