How young is too young?

So my dad got tickets for him, my mom, me, and my husband to the show at Target Field. It’s my first time seeing them, and I’m so excited! The thing is, I’m the biggest fan in the family, and it turns out neither my husband nor my dad actually want to go that badly. They both say, “it’s not that I don’t want to go, I just thought I would stay home so we/you don’t have to get a babysitter.” So then, I thought, why get one at all? My daughter is 6 and loves Foo Fighters, and I could tell she was pretty bummed that she couldn’t go to the concert with us. The tickets do not say 18+. My biggest problems with it in the first place were that obviously it’ll be super loud and then also she probably won’t want to stay until the end, and I’m NOT leaving early. But if the guys don’t care that much about the show, they could leave with her whenever she got tired or overwhelmed, right? And we have several pairs of noise cancelling headphones. She is sensitive to loud noises, plus I don’t want to eff up her hearing, so I am worried the headphones might not be enough. What do you think? Is 6 too young? Should I even bother bringing up the idea to the guys? Would it be a totally rad memory or the biggest pain in my ass?
