MBLAQ more than met the fans' expectations by returning with a performance that is even sexier than the idols' previous songs.

On June 13, MBLAQ put on a back-to-back performance of "Sexy Beat" and "Smoky Girl" on M-Countdown, which was broadcast live.

Coming on stage in full striped suits, MBLAQ filled the stage with sensual choreography involving close contact with female dance crew. Their exposed backs, revealed during the performance, were a surprise for the fans.

"Smoky Girl" was written by Primary with heavy input from Simon D and Zion T, two mainstream hip hop artists in K-pop. With vintage guitar sounds and electronic beats bumping throughout the song, MBLAQ's soulful vocals and balanced rap make a complete performance.

Other performers on M-Countdown included Shinhwa, SISTAR, After School, Ivy, 2PM, EXO, Huh Gak and A-Pink's Eunji, RAINBOW, Nell, Henry, VIXX,100%, Bumkey, BTS, etc.
