There are few musicians online who can compete with Mystery Guitar Man. For his latest piece, he pushed himself and his team to their limits to create a live remix comprised of footage from famous YouTubers playing on screens in real time.

Just to show how complex it was to actualize, he shows viewers how it took over 100 takes to get the videos and sounds to all properly sync up.

Veteran YouTube viewers will recognize cameos from all their favorites, including DeStorm, Epic Rap Battles Of History, Ray William Johnson, EpicMealTime, and more.
