Korea's youngest girl group, GP Basic, will hold a showcase at HEP HALL in Osaka, Japan on May 28th. GP Basic debuted last August with their digital single, "Game". They've decided to expand overseas and put on a showcase for their Japanese fans while participating in broadcast programs. On the day of the showcase, they plan to perform 6 songs total, including their upcoming single, "Jelly Pop" - which is actually scheduled to premiere in June. They are also scheduled to hold an interview as well. GP Basic will be joined by two other girl groups from Japanese agency, Avex. The girls' agency stated, "Officials from the Japanese music industry have shown much interest in Korea's youngest girl group. We are planning to have all proceeds from the Japanese activities and showcase go towards the earthquake disaster relief fund." Source: Star News via Nate
