Travis Tritt says Brantley Gilbert has a thing or two to learn about being a headliner.  After performing ahead of Gilbert at a weekend festival, Tritt tweeted that the earlier acts only had "8 feet of stage," and doubted that Gilbert even "knows how disrespectful his stage setup is to those who open for him."  He continued, tweeting that he means "no disrespect," and that Brantley "deserves" what he's achieved in his career.  But he believes Gilbert and his team "should be a little more aware of how he comes off to those he works with."  Travis added that as a headliner he "always personally made sure" his opening acts had "all the stage space and production that they needed," and he treated his "heroes and peers with respect."
