Pedro Aunión Monroy, an acrobat performing in a six-ply glass cube at an altitude of 30 meters between the Alt-J and Green Day concerts of the Mad Cool Music Festival, fell in front of thousands of people and lost his life. 1975-born acrobats were made by the health teams of the first intervention organization. Aunión, who had been taken to the hospital, was not recovered. It is estimated that the rescue has begun due to the break of the security line attached to the vineyard. The festival management announced that the organization will continue but a short memorial will be held in memory of the acrobat at the opening of the festival's current program. On the other hand, many criticized the social media for not canceling the organization on the death of acrobat.
