So you think they would stay in Europe for almost 4 weeks? Who would pay for their hotels, storage of their gear etc.? I think you don't understand how touring and logistics work...
I don't know how much they cost because that depends on so many elements. I just know that stating some artist ask for more money than the other ones is complete bullsh*t. You're not buying socks. I've had a few chats with people who work in the industry and they all told me one festival can pay a lot more for the same band than a different one. The price is based on so many factors like competition between the festivals, credibility of the festival/promoter, logistics, willingness of the band to do festivals etc. The bands don't simple have a price tag. From time to time there are some leaks that a festival/promoter paid a certain amount but that doesn't mean everyone else pay the same amount.
In what way? That seems like a massive over exaggeration based on the fact that Liam is another headliner.
But then again I also don’t think they are the perfect match for the price they would ask for.
