Brad Paisley opened up the show on tonight's 'CMA Music Festival: Country's Night to Rock' with his song 'Working On a Tan' from his latest album, 'This Is Country Music.'

Paisley kept things simple for the big outdoor show, sporting just a T-shirt, multi-colored guitar and his signature hat as he rocked the Nashville crowd. Though the CMA Music Festival was live over two months ago, it's still new to those of us who weren't lucky enough to attend -- and even as we watch from the comfort of our air conditioned living rooms, it's almost like we can smell the sweat rolling off the artists faces.

The 'Water' hitmaker is currently on his H2O II Wetter and Wilder World Tour with Blake Shelton and Jerrod Niemann, pushing his ninth studio release, 'This Is Country Music,' which dropped May 23.
