EPEX members Wish, Keum Dong Hyun, MU, and A-Min showed a dark and mysterious side in the latest set of concept photos for their comeback album, 'Prelude of Anxiety Chapter 2. Can We Surrender?'. 

The group's upcoming 6th mini album will serve as the conclusion to the 'Prelude of Anxiety' series, which expresses the pains of today's youths through EPEX's unique sound. In the latest set of individual concept photos, the members hint at a quiet tension, dressed entirely in black.

EPEX's full comeback is coming up next month on October 4 at 6 PM KST.
