I beg to differ.Donington '88 ? Awesome !!
If there was ever One festival in time that I could have visited (for both the good and the bad) it would be Monsters of Rock Donington '88. Just Maiden alone headlining on the 7th Son tour but the entire lineup was fantastic.
The festival for me, was and still is Dynamo Open Air. And I'm fortunate to have been there. The first and only time Metallica was on a festival for just one day. (Monsters of Rock was a tour)
