Saturday was another day of surprise duets at CMA Music Fest: Martina McBride with Steven Tyler, Blake Shelton and the Oak Ridge Boys, and Chris Young with tourmate Cassadee Pope. We caught them backstage and onstage during Nashville's hottest weekend of the year so far — both temperature and talent-wise. Joseph Llanes is the only photographer allowed in the backstage hallways of Nissan Stadium, where country music's biggest acts are performing at the four-day festival. He brings us these exclusive photos from behind-the-scenes and from the front row.
