Here is one of my favorite dance companies out there, 1MILLION Dance Studio! They are based in Korea and post all their covers to YouTube. They have a bunch of different choreographers that share their covers, but I think they are all so extremely talented! I would love to visit their studio in Korea, but I also was very fortunate to see them perform live at KCON 2017!
This is one of my favorite covers they did of Believer by Imagine Dragons! I aim to try and learn this piece myself as well!
