8TURN drops new single '[8.X]' and announces 2nd World Tour across Europe and North America

8TURN released new single [8.X] on July 21, the same day the group announced an eight-city European tour for September.

The single has two tracks. Title track Stagefright is an R&B pop song built on a dynamic rhythm, a refined top line, and a hook the group describes as highly addictive. Members Yungyu, Jaeyoon, and Myungho co-wrote the lyrics. B-side 8PM opens with a minimal, chill intro before expanding into a deep-groove dance sound. That structural contrast is what makes it work. Jaeyoon and Yungyu handled lyrics here too (two members pulling double writing duty across both tracks). A music video teaser for Stagefright dropped on July 19, two days before the full release.

[8.X] arrives as 8TURN heads into a busy second half of 2026. The group — Jaeyoon, Myungho, Minho, Yunseong, Haemin, Gyeongmin, Yungyu, and Seungheon — will hit eight European cities in September. Cologne and Berlin in Germany. Helsinki. Paris. London. Amsterdam. Copenhagen. Warsaw. North America follows in October.
