After two years of being MIA in order to meet his mandatory military requirements, singer Kim Jong Gook will be returning, albeit at slower than Turbo powered speed. The 31-year-old singer, who is known for his healthy physique as well as his high-pitched singing voice, will be ending his services on May 23 and will be making a comeback sometime in September. A spokesperson for Kim Jong Gook's label, 101 Entertainment, stated: "When he is released, Kim Jong Gook will be resting and taking time off from working. We aren't scheduling any performances or times in the studio at the moment, but he will be releasing an album sometime in September." What exactly is he taking a rest for? He's been resting this thing he calls a "singing voice" for two years. Looks like the former Turbo member, won't be living up to his name.
