I would like to point out that last year there were 21 bands on the bill and only 4 were Power Metal (Dragonforce, Power Quest, Edguy and Masterplan). Saxon, Blaze and Saracen are Classic Heavy Metal. Nightwish and Mercury Rain - Gothic Operatic, Paradise Lost - Gothic, and all the others a generous mix of styles.
This year we have Bodom (not Power), Edenbridge (not Power), Primal Fear (definitely not Power more trad Heavy Metal), Balance of Power (not Power - compare their latest Heathen Machine CD with Dragonforce and PQ - no comparison in style - so these are trad metal), Threshold are Progressive, Cruachan are pagan celtic folk metal. The only Power metal bands so far this year are Arctica (who even some say are not power) and Intense!
During the 80's and 90's did anyone pigeonhole the lineups of Donington - I don't think so - they were just "Metal" festivals regardless of whether it was AC/DC, Maiden, Metallica, Quo, Gillan, Priest, Rainbow, Kiss, Halen, Motorhead, Leppard, Bad News, Ozzy, Saxon, Megadeth, Queensryche, Black Crowes, Heep, Thunder, Quireboys, 'Snake (so many different styles yet all are just plain "metal" and all powerful or "monsters of rock" in their own right) and this is what BLOODSTOCK is - just a good-old metal festival with the best bands we can realistically get for each years lineup !!!
