Remember your drummer can double as a ticket taker.
With a solid drum shield, your unsightly drummer is safely moved out of the audiences casual vision. But you can also have them keep lost kids until parents can claim them, take tickets, give out information, lost and found, will call. There are endless possibilities .
Balloons are optional, but if you love your drummer, they can be an appreciated touch. Plus if they are shiny they can really help with tricking him into the drum cage to begin with.
