This is SO COOL!  Brad Paisley was performing in his "hangafter" party at Joe’s Bar in Chicago on Saturday night (May 31), along with Randy Houser and Charlie Worsham, when he grabbed a GoPro camera from a fan who was filming Paisley from his front-row seat. Paisley used the small camera as a slide, getting an up-close-and-personal look at his adept fingers in action on his guitar.  Check it out!
