A quarter-million people will pack Gwanghwamun Square tonight for the biggest pop concert Seoul has ever attempted to stage. Seven men reuniting after a five-and-a-half-year break — split between solo projects and mandatory military service — will walk out to meet them.

BTS released Arirang, their first full-length album since 2020, on Friday — 14 tracks named for Korea’s most iconic folk song, produced with the likes of Diplo, Kevin Parker, and Flume. The title is not subtle, and it isn’t trying to be: this is a homecoming record from a band reasserting its Korean roots for a global audience. Two minutes into opener “Body to Body,” a sampled arirang chorus swells over acoustic drums — a statement of intent before a single word of English is sung.

“During my time in the military, I couldn’t work on music even when I wanted to,” Jung Kook told Rolling Stone. “That built up a sense of longing.”

That longing now has logistics to match. Seoul has deployed 8,200 safety staff and 6,700 police officers around the square. Three subway stations are closed, surrounding roads are pedestrian-only, and unauthorised drones will be jammed — precautions sharpened by the memory of the 2022 Itaewon crowd crush. Netflix will livestream the 8pm performance to 190 countries.

Bloomberg estimates the concert will generate $177 million for the city. An 82-date world tour launches in April.

Seoul’s mayor, Oh Se-hoon, promised officials would “do their best to make it both safe and enjoyable.” Tonight, a quarter of a million people will hold him to that.
