Im going to my first concert on the new MM tour, I REALLY dont want to be a dipshit so I need all the concert etiquette dos and donts, particularly related to like signs and stuff? Can I hold one up if im not in dead front? Is it even worth it? Because I plan on making a Eureka themed one (my favourite album), and it would be AWESOME if my favourite band could see the sign i make, so... help. Me. Please.
