Girl group After School are back for another weekend of live promotions with no other national tragedies to interrupt them. With their glossy yet uniform outfits and outstanding choreography, the girl group performs Bang! on Music Bank. Now that the girls of After School finally have their chance to properly promote their latest single, they definitely seem to shine and stand out from the rest of the performers. Their outfits are much appealing to the eye and their choreography is just too sexy to resist. Watch as the girls of After School put on one bangin' performance as they sway their hips and rock their bodies on stage! http://www.youtube.com/watch?v=x53unYaiOPc
