Video Premiere: Rainbow Blaxx - Cha Cha

Another new sub-unit has debuted within the miss managed girl group Rainbow and they are called Rainbow Blaxx. This 19+ rated unit group consist of four of seven members: Jaekyung, Hyunyoung, Seung Ah, and Woori. They've made their debut with the song "Cha Cha".

"Cha Cha" is the title track from their special album "RB BLAXX".

The concept for this group is more on the sexy side. It's a complete (not surprising) change from that horrible other sub-unit Rainbow Pixie and the main groups cute and upbeat tracks "Tell Me Tell Me" and "Sunshine", that was released last year.

Rainbow does the sexy concept really well (ex. "A"), but both the song and video aren't doing nothing for me. I don't find song to be catchy and the video come off a bit trashy, then again it is a 19+.

Check out the video, after the jump.
