From 2011, I believe.

I was in school the other day, on YouTube during my free time, as always, and I rediscovered my favorite dancers AGAIN. How do you even forget something this epic? Idk, I don't know what I was on. But you can't disagree in anyway, this takes a lot of time to master. Dude, this is SEVEN WHOLE MINUTES of choreograph to dubstep music. Dubstep is already an incredible genre by itself. If you can dance to it, you're lucky. But to completely choreo something to each sound in a dubstep song, takes so much more than 7 minutes. Simply amazing. 
Whatever. Enjoy.
