The two members of the sexy Sistar unit group Sistar19, vocalist Hyo-rin and rapper Bo-ra, made their comeback official with their latest EP album “Gone Not Around Any Longer.”

“Gone Not Around Any Longer” was released on Thursday and its title track received a perfect “all-kill,” sweeping all the main real-time local music charts, making it the second certified all-kill of the year after Leessang’s hip-hop single “Tears.” The newest release from the duo is a mid-tempo pop song featuring Sistar’s trademark sexy choreography.

Sistar19 paired up with Korea’s hit-making music producer Brave Brothers once again for the making of the album. Brave Brothers was the man behind the idol group Sistar’s hit track “Alone,” which swept various charts upon its release.

This comeback album marks the second release by the group since the announcement of their debut and popular first single “Ma Boy.” After the 2011 debut, Sistar19 suspended its activities to focus on the promotions of the four-member group Sistar and releasing the album and title single “So Cool” in August of the same year.

“So Cool” took the No. 1 spot on the Billboard K-pop Top 100 charts, which was a first for the girls.

Last year, Sistar released two albums, “Loving U” and “Alone,” with the latter setting a record on the K-pop Billboard charts for keeping the chart-topping position for the longest period.
