BTS, the globally acclaimed K-pop group, commenced their highly anticipated 'ARIRANG' World Tour on Friday at Goyang Stadium in South Korea, despite facing heavy rain during the performance. This marked their first major tour after completing mandatory military service. The concert lasted over two and a half hours and featured a 23-song setlist, including tracks from their latest album and popular hits like 'Idol', 'Dynamite', and 'Butter'. Notably, they performed 'Come Over' live for the first time. The event attracted around 22,000 attendees, while approximately 200,000 fans gathered outside Gwanghwamun Square during a prior performance in March. Analysts predict the tour could generate up to 2.7 trillion won (roughly $2.1 billion USD) in revenue, potentially making it one of the highest-grossing tours in history.
