UNIQ made their strong debut in both Korea and China last year and returned to the K-pop scene with the 1st mini-album, "EOEO." The title song "EOEO" is a dubstep-based hip hop number with a catchy, sexy saxophone melody and elements of urban R&B.Derived from the sound an ambulance siren makes, the constantly repeated refrain "EOEO" is particularly impressive.
