3. Little Big Town and Ariana Grande
CMA Awards, November 5th
If more proof was necessary that the layer-cake harmonies of Little Big Town can enhance anything, look no further than the quartet's kicky vocal teamwork with the pop starlet on her hit, "Bang Bang." Bedazzled in light-up suits that changed colors, backed by a drumline, and throwing themselves wholeheartedly into the silly, saucy jam, LBT's Jimi, Karen, Kimberly and Phillip were clearly having a grand old time backing up the petite powerhouse. Was it country? Not even a little bit. But it was a blast of fun on an otherwise mellow show.
