NRG

NRG is a South Korean boyband. Their name is an acronym for New Radiancy Group. Originally a five-member group, they became a three-member group when the leader Lee Sungjin left to pursue a career in acting and as an announcer and Chun Myung Hoon left to produce music. After the not so popular group of 3, the old members returned for the next fourth album, but after the death of Kim Hwan Sung in 2000 the group was down to 4 members. With the 4 members, they had a hit success on their 5th album and later 6th album but after the departure of Moon Sung Hoon in 2005, it is now a three-member group again.
