We guarantee you've never been through a more painless process in your life - the audition is just to see what part we should give you. Your section leader will be your surrogate parent. I don't have an instrument. You have a few options here. We in the YPMB wear white jeans with our band blazers, which you will rent from us later.
White pants work too.
We know, we know, they're not horribly fashionable, but they look great on the field. So if you can find some white pants, snag them. And if you still really want to bring something, we like peppers and onions on our pizza. We'll attach you to a section leader and make you feel at home. I still have a question.
