Rookie boy group AA made their debut at the '2011 K-Pop Super Concert'.  The 5-member idol group has been creating quite the buzz with their catchy new 'sweep choreography'. On October 28th, the boys took their first step as singers.  AA performed for the first time in front of over  20,000 revelers catching performances by the latest K-Pop stars.  The boys were joined by labelmate senior and actress Ha Ji Won, who performed a sexy and powerful wave right alongside the rookies. AA performed their self-produced debut track, "It's Because I'm Crazy".  With a cuter choreography that showed off their diverse charms, they also performed a track off of their upcoming re-packaged album, "Okay About It".  More than anything, they impressed the crowd with their stable live performance skills. In a subsequent interview, the boys stated, "We were really nervous about our first stage, but Ha Ji Won's support and our past rehearsals really helped a lot. We'll take in the advice given to us by seniors like Ha Ji Won and Lee Jong Suk and continue to work hard." AA will be debuting on the November 4th episode of KBS's 'Music Bank'.
