So , basically I'm here for this one thing. This weekend I'm gonna assist at my first metal concert. A folk metal festival which Im really anxious to go. But as I said is my first metal concert and I'm not sure what I should do. Throw myself in the mosh? Enjoying it without risking for now ? Is a folk metal festival so I'm gonna dance a lot, but how ? I mean,what if I'll look like a fool out there without having an idea about how to behave ? Some advices from people with would really help.
