After the 2014 festival also sold out before the weekend, selling 73.000 Combitickets, 2015 was the first non sell-out in several years with around 65.000 attendees. According to the organisers this was due to the strong competition from other festivals that year and the subsequent weaker headliner line-up (Placebo, Florence + the Machine, Materia). In addition in the same year an elaborate contactless payment system was used on site rather than cash.
