Back in 2010, this artist was performing the State Fair concert in Pueblo, Colorado. I guess a guy from the crowd told this artist that performing is easy. Well then, the artist pulled him up on stage and then gave him his guitar and mic and told him to do it then. What happened next was nothing short of amazing. The guy sang a combination of 3 songs and blew the crowd away so bad that the artist completely walked off stage while he was singing.

Who Did It? Blake Shelton
