Last year, he launched his own festival, BludFest, in Milton Keynes, which was criticised by some after long queues and a lack of water caused fans to pass out and miss the concert.
With tickets sold for £73.25 for this year's festival in the Buckinghamshire city, Yungblud said he felt more expensive events had become "a thing of privilege" that "do not represent real people".
"I cannot play a festival where it's like 800 quid a ticket," he said, adding that artists like Coldplay were welcome to join the event.
