Price information:

There are different prices: 10€ for students 15€ standard ticket 20€ for sponsors Sponsor ticket: the higher purchase price is not associated with any special advantage for the buyers. If you think that Bergisch Metal is worth more than the 15 euros, donate 5 euros to enable the event to continue at a high level without having to raise the admission price for everyone and also to compensate for the reduced income from the student tickets. Student ticket: no student ID is required at the time of purchase, but it does have to be presented at the entrance. This means that anyone presenting a student ticket at the entrance must be in possession of a valid student ID. Otherwise, the difference to the standard ticket must be paid in cash. Standard ticket for €15: I think that's self-explanatory. The ticket for all adults who are not students.
