4minute's HyunA finally performed her first solo debut stage on yesterday's Music Bank with her first single, Change. Featuring Jun Hyung from BEAST, HyunA visited Music Core for the first time alone, to have a second-go at her solo stage! With Change climbing up the online music charts rapidly to be the first big hit of 2010, we can easily claim that HyunA's solo debut has been a success so far. Full of powerful choreography, she totally killed it again! Check it out! http://www.youtube.com/watch?v=ht5E03LaI84 Make sure to join the 4-minute fan site!
