As international K-pop fans become more and more familiar with boy group BTS, the idol group has had even more opportunities to travel all over the world.

BTS uploaded footage of their various practice sessions in Brazil, Korea, Germany, the U.S. and Stockholm on their official YouTube channel, showing the world that they're on their way to spreading the true Korean wave, according to the Korean publication Osen.

The footage was taken from their recent tour in Europe and South America, along with their preparation for KCON 2014, which was held in Los Angeles. The boys of BTS reportedly practiced for 16 hours a day for their recent performances.

BTS released their new track "Danger" on August 20 and are currently promoting the upbeat song as well as their latest album.

BTS, which consists of members Rap Monster, Jin, Suga, J-Hope, Jimin, V and Jungkook, was formed and trained by their current management agency Bit Hit Entertainment. The boys made their debut last year with the first part of their mini album trilogy "2 Cool 4 Skool."

The seven-member idol group has been recognized for their musical talent, even being recognized as "Korea's hottest new rap group" by Vice. Despite their rising popularity, the boys have had to learn quite a bit to earn the title.

Since their debut, BTS set the goal to be as different as possible in the Korean pop industry, as their recent L.A. trip to meet with various American hip-hop artists indicates. The group's reality show titled BTS American Hustle Life shows fans "exactly what it's like to make it in America as a rap star" because unlike other K-pop groups, BTS wants to reach that caliber.  

In preparation for BTS' new album "Dark & Wild" which was released on August 20, the boys even met up with one of 90s hip-hop's legends, Coolio.

BTS, who celebrated their one-year anniversary since debuting on June 13, has truly grown in their field, all because of their hard work and the support of loving fans.

"Applause for BTS, who worked so hard for a year! Applause for the fans who always show their support! Please be with us in the future as well," tweeted Big Hit Entertainment, according to Allkpop.
