Vocal duo Davichi has announced that they'll be holding an end-of-the-year farewell concert on December 27th. The concert will be called 'Bright as Jade' and will commence at 8PM KST, lasting for two hours. Popular girl group, T-ara and 'Superstar K2' winner Huh Gak will also be participating as guests. The duo plans to shine brightly on stage by pouring deep emotions into their songs. Instead of going for a flashy concert with lighting effects and whatnot, Davichi will deliver a more low-key, if not emotionally enriched performance. With T-ara's powerful dance choreography, Huh Gak's rich vocals, and Davichi's sweet harmony, fans can expect a hot performance this December! Source + Photos: Sports Chosun via Nate
