Defqon.1 in Biddinghuizen
Defqon.1 is a four-day hardstyle music festival held each June at Walibi Holland in Biddinghuizen, produced by Dutch promoter Q-Dance. Billed as the world's leading hardstyle festival, it draws around 65,000 fans a day across more than fourteen stages, running from an opening event called The Gathering through a closing set known as the Closing Ritual.
Defqon.1 grew out of Q-Dance, a Dutch promoter specializing in hardstyle and hard dance music, into what is now widely regarded as the largest hardstyle festival in the world.
