With his face hidden under a baseball hat for most of the night, Gilbert rocked out for just more than an hour with the deafening country rock that has earned him a loyal fanbase. Most of his songs boast about tough country living, as he appropriately growled through “Hell on Wheels,” “Kick It in the Sticks” and “My Kinda Party,” (also made a hit by Aldean, and written and previously recorded by Gilbert). And for those who don’t technically live south of the Mason-Dixon line, no worries — Gilbert is glad to include everyone. On “Country Must Be Country Wide” — his new single inching toward the Top 20 on the Billboard country chart — Gilbert points out that no matter where you are, “in every state, there’s a station playing Cash, Hank, Willie and Waylon.”“This is the part of the night where I get to have some fun,” he declared in the middle of the show before telling an especially rowdy group near the stage to “take it outside.” Minutes later, he broke into . . . “Take it Outside,” reminiscing about when real men respectfully paid their tab, left the ladies in the saloon and went elsewhere to beat each other up. But for all the tough edges, Gilbert sings with unexpectedly raw conviction on songs about relationships, such as the surprisingly sweet “My Kind of Crazy” and a wry tune about how “it had to be hell on an angel lovin’ the devil out of me.” With his latest single gaining momentum and the rerelease of his aforementioned 2010 album, “Halfway to Heaven” this fall, Gilbert seems poised to break into the mainstream. But there are benefits to living on the edge. At the end of the high-energy show, Gilbert’s encore of “G.R.I.T.S.” (about the many attributes of a Girl Raised In The South) whipped the audience into such a frenzy that people started hurling themselves toward the stage while crowd surfing, with varying degrees of success. It’s hard to imagine that at a Jason Aldean show.
