Been a few years since I was last at it, don't remember them doing it then must be relatively new.

99% sure I am going to go to this next year, looks like a perfect setup to be honest, they get a lot of the same bands as Wacken, the ticket is 100 euro less, and the glamping is cheaper, and it's about an hour away from Brussels airport.
Brutal Assault looks great but I don't fancy bussing it in & out each day.
I am too old for normal camping in a field
