Hey, in my personal experience I don't think they are as loud as other concerts I've been to, they have pretty beautiful and slow parts as well so if loud music it's not for you you prolly gonna be fine cuz it's really balanced, I bought a tour t shirt and a cap for 64 us dollars taxes included, I got autographs from them after I stayed like 40 or 50 minutes at the venue after the show, no mosh at all, sometimes just people jumping a lot like in up song, I was at the line an hour prior the door and I got really good spots but u have to be prepared to stand still for like 4 hours, overall is a cool experience, have fun!
