The correct tag for the k-pop duo is Trouble Maker. A mental plague experienced by groups of people at once, predominately in basements. An amalgamation (read: rip-off) of many notable sounds, and some not so notable sounds. A whole whose parts share the same discomfort and misery day after pointless day. A band that makes music. 2007-2012. Members of Troublemaker now play in Manalive and Big Bad Wolf.
