Watching XG dance reminds me of when I first discovered Jabbawockeez and Quest Crew on MTV's America's Best Dance Crew. When I saw XG's dance practice video for Tippy Toes I was amazed. Then I saw their other dancing stuff and their dance performance for Hesonoo & X-Gene literally had me speechless with my mouth open for almost the entire video and that was after I already had seen their MOVE series which is already insane
