Jong-Kook Kim

Kim Jong Kook first entered the Korean music industry in 1995 as a member of the group Turbo, which became immensely popular for their catchy music. After the group disbanded a few years later, he became a solo singer in 2001, mostly concentrating on ballads. Although his unusually high tone of voice is often joked about (with many stars jokingly calling it a "mosquito voice"), he has had many hit singles and has also been a frequent guest on many variety shows, most notably X-Man. In addition, his muscular body is often considered one of the best in K-pop, due to constant weight training.
