It is the strong body tension, the exact beat synchronicity of moving like a goovy drummer playing his beat. Best performance and choreo I've ever seen. You guys make others looking like dancing cooked noodles!
Hey Sam! You're choreography is so awesome especially The Other Side by Justin Timberlake choreography . Could you please turn-on the comment (for that video) so that you know how many people wanted a tutorial for that. Thanks ;-)
