you should go; like you said - I'll be a new experience, and if you don't have a good time then you'll know that concerts are not your thing
I personally like going to concerts, even though people usually dance and sing and I just stand there motionless like a statue, but I always have fun
one crucial piece of advice - buy earplugs if you can; concerts are super loud and can damage your hearing (there are special earplugs for concerts that don't block the music completely) - I went without them last time and had tinnitus afterwards (it passed after a day, but was annoying as fuck, like I had a cricket in my head)
oh, and don't take too many pictures, people who keep flashing their phone cameras are annoying; be mindful of the crowd and don't get crushed; don't drink too much unless you want to keep going to the bathroom
I'm not a fan but they're decent
do you have numbered seats or is it more of a general admission type of thing? because if it's GA you might want to arrive early
and don't bring any big bags or backpacks or anything made of metal (you might want to check avenue's website for rules and regulations)
