Boom will be reporting for his mandatory 22 months of military service on October 29, 2009.

The former hip hop act began his career in 2006 with “Boom Up” but did not reach his career high until 2008 with his appearances on variety shows such as “Starking”, “Champagne” and most recently “Strong Heart”.

Hopefully his military service won’t hamper his comeback two years later like it did with former NRG member, Lee Sung-Jin, who ironically was replaced by Boom as the frontman comedian on variety shows.

Check out his first music video “Boom Up” featuring a youn flower boy Kim Bum and compare the transition between his “gangster” self to his now comedian self in his newest corner “Boomkigayo” on “Strong Heart”.
