So, as a broke teenager, i need cash. We have a festival in my small, Minnesota town next week, and i was thinking about trying my hand at street preforming. I was wondering, do i need a license? If so, where do i get one, and how much does it cost? Is preforming in the streets generally accepted? What should i use as a tip jar? Please don't say your guitar case, because all i have is a gig bag, if it was a hard shell, sure! But, alas, it is a gig bag. Well, any advice is appreciated.
