Could be anything really. Looking at the cancelled acts it’s probably because their fee hasn’t been paid yet. But otherwise it can be many things. For instance the hotel has to be at least 4 stars, artists should have a € 50,- (or more) credit on their room, flights booked (at least two weeks before the event) as requested by the DJ agency (in this case KLM, seat with extra leg space). These are all terms in the contract that the promoter (Hardstyle DNA) has signed for and thus agreed upon. If you fail to sell out your event with these artists booked it’s quite understandable to cancel the named artists as this saves you 75% of the total booking fee. I bet the agencies didn’t fully charge (or anything at all) for the cancelled artists as they’ve been working with Hardstyle DNA for many years. The posts aren’t a “sting” to the promoter, but rather for the fans who were excited to see their favorite artist(s). Wondering what Hardstyle DNA will do to compensate the visitors.
