Depends on the type of line-up. I have seen the ages from all ages (12-17) to adults 18+.
Some events you can attend and be just 12yrs old. Best to check each individual event or call night of.
Lookd like everone here got it, but ages are set by the event, although it is usually 18+
Depends on the show always check the ticket. The seller will know if all ages or 18 +
