Secret's Song Ji Eun began her solo activities with a performance with Fly to the Sky's Hwanhee on KBS 2TV Music Bank. The track, which was released on the 15th, experienced an explosive reaction from the public as it ranked #1 on realtime charts of online portal sites and was one of the most searched keywords. Perhaps it's because the R&B singer wrote the lyrics to the song himself, but both he and the member of Secret radiated an emotional intensity that was appropriate for the sad ballad song. Additionally, the harmony of Hwanhee's deep, powerful pipes and Song Ji Eun's soft, angelic vocals made for a performance that was enjoyable to listen to. Based on her performance tonight, I think it's safe to say that her vocal abilities are no longer a secret. Stay tuned for more performances from her (and Hwanhee) on MBC Music Core and SBS Inkigayo this weekend. For more on Secret check out SecretFour.
