My First Major Concert!!!!!

So Asking Alexandria is going on tour with Memphis May Fire, As I Lay Dying, Suicide Silence, and Attila. I'm freaking out right now because my mom bought me the ticket two weeks ago and i'm still so excited. I live in NY so i have to wait until December to actually go to the concert but this is official my first major concert. I've been to underground shows but this is going to be packed. I mean come on all these amazing bands in one place!!!!!! I can't wait until December i want to go now. I'm literally obsessed with Memphis May Fire right now and i'm freaking out. So is there anything i should know about going to a concert? i've never been to anything like this and would like to know what you guys think.

P.S. This concert makes up for me missing Pierce The Veil live. oh and you guys could probs still get tickets, here's a link : http://www.askingalexandriaofficial.com/events
