There are concerts that are fun and there are concerts that kick your ass. If you were at the sold-out U.S. Bank Arena Friday night for the opening date of The Black Keys first headlining arena tour, you probably got your ass kicked. First up, Arctic Monkeys caused a ruckus on the floor. Most (but not all) of the folks in the seats wandered around aimlessly or sat there, watching listlessly. There was certainly uproar in front of the stage, though. But as the English boys played, sang and sassed, the crowd in the arena filled in and loosened up. It helped that their lighting guys strobed the shit out of them, too. The seizure-inducing lights may have been Morse code for “Love Arctic Monkeys. Swoon over our accents.” If so, it worked. By the time Arctic Monkeys closed with “When the Sun Goes Down,” the crowd on the floor had nearly doubled and, at the very least, those in their seats were nodding their heads and smiling. Those boys put on a fun show. After spending the entire intermission only getting halfway through the beer line, nearly everyone gave up and fled to their seats when The Black Keys began. Not that anyone sat, though — they were all too busy dancing and freaking out. Strictly speaking, The Black Keys may not be from Cincinnati but it’s safe to say we treat them like hometown boys, anyway. Dan Auerbach (singing/guitar) even recalled playing Southgate House a few years ago. Upstairs. In the small room. From a titanic disco ball that lowered from the rafters (for only one song) to the graphics on the screens behind them, the show was far different from their days playing tiny rooms. With each beginning there was an outburst of recognition. The middles of songs gave way to dancing, flailing and air guitar (or drums) and each ending note was drowned out by thousands of shrieks, whistles and catcalls. Two things were learned last night. First, if you have any doubt about the amount of noise that one guitar and a set of drums can make, go see The Black Keys. Their albums don’t do justice to the sheer volume Auerbach and Partrick Carney (drums) are capable of producing. Second, you haven’t lived until you’ve heard an entire arena try to whistle. If you weren’t there, you missed the best kind of Friday night possible. If you were, you’re probably already making plans for the next time The Black Keys come to town.
