CORTIS, under Big Hit Music, released the extended version of their second mini-album titled 'GREENGREEN_playextended' on August 24 at midnight to celebrate their 1st debut anniversary. The extended album features two new tracks: 'PACK IT UP' and 'MONEYMONEYMONEY'. The group first performed the new songs during a concert held at Korea University's Hwajung Gymnasium in Seoul on August 23. All members participated in writing and composing the new tracks. According to their agency, the extended album carefully selected two songs from previously unreleased tracks that best reflect CORTIS's current artistic direction, presenting the team's honesty and authentic experiences in greater depth. Following an additional Seoul concert, CORTIS will continue their tour in Yokohama, Japan in September.
