9MUSES Returns With Stunning "Sleepless Night" MV

9MUSES are back!

On November 23 at midnight KST, the girls dropped their new fifth mini album “LOST,” along with the music video for the title track “Sleepless Night.”

“Sleepless Night” is an emotional dance number with a beautiful piano melody, making it the perfect combination of soft and strong elements. This is 9MUSES’ first time to collaborate with hit producer Brave Brothers, who is probably best known for working with SISTAR, 4Minute, Teen Top, and After School.

For 9MUSES, 2015 has been a year of comebacks: “LOST” marks their third round of promotions this year, following “Drama” in January and “Hurt Locker” in July. The album consists of six tracks, and one of them entitled “To. ?” has been written by the members.
