My niece from Taiwan sent me one of their videos. They are a Korean K Pop group. They are as cute as a bugs ear. I've become a fan of a girl group in my old age. The Korean music scene is reminiscent of America in the 50s. As Brian Wilson said, "for reality, it's not for me and it makes me laugh, for Fantasy World and Disney Girls, I'm coming back"
My wife of 20 years is Korean and my 11 year old daughter is into K Pop. When I played the video for her she was like, "duh dad, that's f(x)." She knows all about f(x) (the name of the band). According to my daughter two of the girls are not Korean but are Chinese while a third is Korean by heritage but was born and raised in San Francisco. In Korea bands are formed by the music companies, much the same way that Disney and Nicolodian create bands for their TV shows.
