The most talked about musical performance at the 2017 American Music Awards wasn’t sung in English. When the band BTS took the stage at the Microsoft Theater in Los Angeles, California, the screams were deafening. Fans chanted the names of the seven performers to the rhythm of the song. The cheers nearly drowned out the singers’ voices! Millions more watched the performance on TV.

The group, also known as Bangtan Boys, became the first Korean popular music act to perform on a major American award show. Last year, BTS climbed the music charts, sold out U.S. concert arenas in minutes, and took home the Top Social Artist award at the 2018 Billboard Music Awards.
