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
