B1A4

A new group debuted now in 2011, in April. And i must say, they do have a lot of charisma. Probably why I fell in love with them, the instant I saw them on M countdown. And who can not fall in love with the song O.K - It is a total summer tune, you just wanna shake your entire body along with. 

Try listen to it, without dancing?
B1A4 - O.K (2011)

Are you not sitting with the biggest smile on your face right now? Your not? ... Shame on you. *blink*

B1A4 is named that way, because of the members having one person with blood type B, and four persons with blood type A. So from that you can guess how many people the group holds. 

JinYoung (Jung Jin Young) is the leader and lead vocalist, born in 1991. He is blood type A

CNU (Shin Dong Woo) is vocalist and rapper, born in 1991. Blood type A. 

Sandeul (Lee Jung Hwan) is main vocalist, born in 1992. Blood type A. 

Baro (Cha Sun Woo) is main rapper, born in 1992. Blood type B. (woho there is the B) 

Gongchan (Gong Chan Shik) is vocalist, born 1993 and therefor the youngest one. With blood type A of course. 

You cant find much info about them right now, since they are very new. Some cute guys with a lot of charisma and great tunes, that I look forward to see more of - anyhow. 

And finishing of with a calmer song -

B1A4 - Only one (2011)
