Korean girl trio Ladies’ Code is set to return Tuesday at midnight with the album “Myst3ry.”

The girl group has already released two teaser videos for “Galaxy,” a mid-tempo song that invokes a gloomy and dreamlike mood. This comes in contrast to their previous up-tempo dance numbers including “Pretty Pretty,” “Bad Girl” and “Kiss Kiss.”

Having debuted in 2013, Ladies‘ Code is composed of singers Ashley, Sojung and Zuny. Formerly a quintet, the group suffered a car crash while traveling together in a van in September 2014. EunB died at the scene, while RiSe died in a hospital four days later. The group decided not to recruit new members in place of the deceased members.
