Wondering what MC/singer�Boom has been up to these days? On July 29th, a set of pictures were uploaded onto an online community board under the title, 'Sergeant Boom, who we will see soon'. In the pictures, Boom could be seen with his usual lively energy, confidently conquering the stage. Because of the casual nature of the photos and the civilian clothing he sports, it almost looks as if Boom is already an ordinary citizen. The pictures were taken for the public broadcast of the Armed Forces channel. Boom is a popular hip hop singer and MC, his entertainment career was put on hold when he enlisted in the Korean Navy back in October of 2009. Boom will be officially discharged on August 29th.
