Hallyu group Super Junior has announced that they will be releasing their sixth studio album before leader Leeteuk leaves to serve his two-year military service.

Super Junior recently held their ‘Super Show 4’ encore concert which took place in Seoul Olympic Park Stadium on May 26 and 27. On the last day, Leeteuk surprisingly revealed, “We are working on our sixth studio album which will be released before I leave for military service.”
