How did Korean pop band BTS come to headline one of the world's most iconic stadiums? Prepping to play a sold out Wembley the band, and fans, reflect on their path to pop-stardom.

BTS are the first Korean act to reach number 1 on the Billboard charts in the US, and the first group since The Beatles to earn three number 1 albums in less than a year. They have featured on Time magazine's most influential list and they have performed on some of the biggest TV shows in the world from Graham Norton to Jimmy Fallon. They have even spoken out about mental health at the United Nations.

When BBC Radio 1's Adele Roberts first met the seven member K-Pop boyband BTS, they had never been to the UK. Now, two years later, she meets them again as they are about to become the first Korean pop group to headline Wembley Stadium, selling out two nights and playing to over 60,000 people.

Their success has been observed by tens of millions of people, not least Adele Roberts who was first to play a BTS track on Radio 1. In this programme, Adele takes a look at how the band's journey began and how they have come so far in such a short space of time. She speaks to the choreographer behind their famous dance moves, finds out about the role that fashion plays, and speaks to their devoted fans. BTS' fanbase call themselves the ARMY and are a powerful force to be reckoned with, helping the band's latest single 'Boy with Luv', featuring Halsey to become the first track by a K-Pop band to make it into the UK Top 20.

Adele asks what's next for this K-Pop sensation as we see them play Wembley Stadium for the very first time. Show less
