It's an Evanescence concert.
Well basically my work experience placement (for which I have to wear a suit and HAVE to attend it on that day) is 5 mins away from the venue so I don't want to go home and get changed as I want to get near front of queue when my day at the placement is over.
I'll probably have to wait in the queue outside for about 2 hours as well but I heard it gets really stuffy and warm inside the venue (Birmingham o2 Academy)where it is.
