Less than a month after the release of summer EP “Touch N Move,” the members of sexy K-pop quintet Sistar will release yet another album next week, the group’s agency, Starship Entertainment, said Tuesday.

Officials at the agency said the upcoming EP titled “Sweet & Sour” would drop on Aug. 26. The album will feature six tracks: two new singles as well as “I Swear,” composed by popular producing duo Duble Sidekick; “Hold on Tight,” composed by hip-hop agency Brand New Music; and remixes of the group’s most recent lead single “Touch My Body” and past hit “Loving U.”

“Duble Sidekick spent a lot of time working on the single ‘I Swear,’ which is why we decided early on to select this as the upcoming album’s lead single,” the agency’s statement said.

The soon-to-be-released single is said to be a house dance summer track. The four ladies of Sistar are currently in Saipan filming the track’s music video, which is also expected to be released on Aug. 26.
