BTS throws free concert to promote South Korea’s World Expo bid

K-pop mega-band BTS reunited on Saturday for a free concert in Busan to support South Korea´s bid to host the World Expo, four months after the musicians announced they were taking a break from group activities.

Some 52,000 excited fans, many dressed in purple -- the band´s official colour -- gathered in the Busan Asiad Main Stadium on Saturday evening, with local reports saying hotels near the venue were fully booked.

The night before the concert, major roads as well as a number of tourist spots in the port city, including the Gwangan Bridge, were lit in purple in honour of the septet.

BTS are credited with generating billions for the South Korean economy, and their label enjoyed a surge in profits despite holding fewer concerts during the coronavirus pandemic.

In June, the septet dropped the bombshell announcement that they were taking a break as a group to pursue solo projects.

Aside from music, the band has championed global progressive causes, from the Black Lives Matter protests to raising awareness on mental health to battling anti-Asian racism in the United States.

"BTS, if you are getting this message, thank you. Thank you so much for everything," an emotional fan from the US told a local broadcaster in Busan on Friday, adding she was inspired by their music when things were difficult.

"I will never give up on myself because you never gave up on me."
