The laws are going to vary from state to state AND whether or not you are an employee versus working as an independent contractor. In many states, it is illegal for minors to be employed by “entertainment” venues under the age of 16 (movie theaters, etc.)… mainly because the category is so overused for other establishments. If you are working as an independent (meaning, you have your own business and are being paid per job) then the only laws you need to worry about are if you are legally allowed to be in the establishment. What you may want to consider is having your parents form an LLC, negotiate the gig through the LLC, and then you act as an employee of the LLC. This will protect you, and your family, from any lawsuits that may arise and will eliminate you from the employee laws.
