MAMAMOO gave a sneak peek of the title track "ILLELLA" from their upcoming 12th mini-album 'MIC ON.'

"ILLELLA" is the Korean phrase meaning "To cause trouble," or "Do something great." Like the title of the track, the members are ready to cause havoc with their powerful voices and inescapably gripping charms. In this latest teaser, the girls are more charismatic than ever as they get ready to "ILLELLA."

Meanwhile, MAMAMOO's 12th mini album will be released on October 11 at 6 PM KST.
