I was totally blown away by this, I am familiar with mashups, but what this guy did puts it in a total new perspective. He took small clips from YouTube where people play an instrument, and then build incredible tracks and videos from these clips. You just have to see and listen to believe, but, I can tell you: this is really incredible. Is this the emergence of a new Music Genre?
