Due to the naval ship tragedy, many live music programs have gone through a period of darkness. But now that the time for grieving is over, After School returns to the stage with Bang! on Music Bank! For about a month now, Music Bank has been avoiding broadcast out of respect for the dead. But with the national memorial service out of the way, After School is finally given the opportunity to do some live promoting. After School brings it on back to you with their drum thumping track, sexy outfits and amazing choreography. Watch as the girls strut with quite a bang on stage. http://www.youtube.com/watch?v=3PgMsf6x0B4
