One of my favorite things at a concert is when the artist interacts with the audience. I'm not talking about them shouting out "How we feeling Tuscaloosa?!" No, that doesn't count. What I'm talking about is when they stop what they are doing to personally talk to someone in the audience, even invite them on stage for a little one on one time. It shows that the artist really love their fans.
Take for instance when Jared Leto stopped his Thirty Seconds to Mars show to talk to seriously the cutest little kid EVER!
