A staple of K-pop concerts is the meticulously rehearsed choreography and CD-quality vocals prepared for every performance of the night. For their New York City debut, BTS did that, of course, but also showed a more relaxed and freer side of themselves that made the show that much more memorable -- even with an abrupt finish.
Introducing themselves to the sold-out Best Buy Theater crowd in matching military jackets, the septet opened with "N.O" that showcased their polished, hip-hop-inspired choreography from the get-go with B-boy moves, slinging hats around their body and, at one point, member Jimin flipping over his band mates. But as the guys moved into third song of their Red Bullet setlist, "We On," they moved away from the in-sync moves and instead freestyled throughout the whole performance -- which is rather rare for K-pop acts and even more rare that they can look natural doing it.
