"Row Zero" refers to a separate area directly in front of the stage at Rammstein concerts. The tickets for this "exclusive" zone cannot be bought, you have to be invited.
Reports suggest that only women are recruited for this. Propeller Music & Event GmbH has decided, after consultations, that there will be neither a 'Row Zero' nor afterparties at the concerts in Munich. The company anticipated potential regulatory requirements and has ruled out a return of tickets.
