Luke Bryan is considered the King of Bro Country, a title he seems to embrace while also hoping to be treated as a serious artist. Count all the lyrical references to alcohol, trucks, gurrls (not just girls), rural settings and catfish you like. Thing is, the thousands of people who will come to AT&T Stadium want to have a good time, pure and simple. This four-act blockbuster show is what country music sold to a mass audience looks like these days, but it gets some real credibility from openers like Little Big Town and country’s latest ordained savior, Chris Stapleton. Most mainstream country music is for people who grew up on Garth Brooks, Bob Seger, Tim McGraw and Def Leppard, and weren’t afraid of hip-hop, either. Plus, it’s family entertainment. As easily mocked as the bro country genre is, it sure isn’t losing any steam by snark from those who don’t get it.
