In 2004, Defconn received theKorean Music Award for "Best Hip-Hop Album". His songs are mostly comical, sometimes involving lyrics about sexual attraction and wishing for more popularity. One song of his, though, centered on theYangju highway incident in which two South Korean girls lost their lives to an American militarytank, which sparkedanti-American sentiment in South Korea at the time. He is one of the better known underground rappers in South Korea due to his parallel career as anMC.
In 2011, he became the host ofMBC Every1'sWeekly Idol alongside entertainer and comedianJeong Hyeong-don, a show which was extended from an original six episode special to a weekly show that continues today.
In June 2012, he and Hyungdon formed a hip-hop collaboration calledHyungdon and Daejun.[2]
Defconn is a founding member ofMBC'sI Live Alone, a documentary-style variety program focusing on the real lifestyles of men who live alone. The "Rainbow Club" – a self-designated nickname for the show's hosts – includes both men who are unmarried and men who live alone because their families live overseas.[3] Defconn left the cast in July 2014, citing that he was moving in with his brother and would no longer be living alone.
In November 2013, Defconn became a cast member for the third season ofKBS2'sHappy Sunday segment2 Days & 1 Night,[4] and he remained so until 2019, when the third season ended.
