DOH I didn't see this post until now. With bigger bands, they RARELY let just anyone take photos without a photo pass. It's always up to the band and their tour manager. If it is a smaller band, they usually don't mind. But at this show, I'm HIGHLY doubting people can take cameras in. I'll try and find out for you.
One question... What kind of camera are you trying to bring in? A small point and shoot, a disposable, a small one with a zoom, a big one like mine?????
