K-pop supergroup BTS have returned after a four-year break with a massive free comeback concert in Seoul, where thousands of police locked down a central boulevard for the Netflix-exclusive spectacle that drew tens of thousands of fans.

“Annyeonghaseyo! We’re back,” RM, the band’s leader, told the crowd, using the Korean word for “hello”, as they opened with Body To Body, setting off delirious screams from fans waving purple-and-red light sticks and thrusting smartphones into the air.
