Heading into the North Charleston Coliseum Saturday night for the Rascal Flatts concert, I saw surprisingly few cowboy hats, but a shockingly huge entourage of tractor trailers and tour buses — there’s no doubt these guys are in the big time. My heart broke when I walked in just as opener Jessica Simpson walked off the stage, but I felt much better when I was escorted to my front-row seats. Gary LeVox (in a sequined ensemble), Jay DeMarcus (the jokester), and Joe Don Rooney (looking hot as usual), along with their band of mostly South Carolina-based musicians, played some songs from their forthcoming album Unstoppable, as well as older crowd-pleasers like “These Days” and “Bob That Head.” They said they’d give us our money’s worth, and that they did, with an energetic two-hour long performance. The night ended with a shower of confetti and patriotic-colored balloons, and the entertainment continued as I watched people scramble for a keepsake. They proudly carried the giant balloons to their cars, then seemed heartbroken when they popped. Oh, so sad.
