Bad move for Dragonforce. For the most part, the WRONG people will be at the show. Not many (some, but not many) true metalheads go to Ozzfest. The price is too high to see 2 bands that I really want to see. And I HATE ampitheater venues. Unless you're in the pit, the view is horrendous.
The points already made about no one seeing the first main stage band is true. I went to Ozzfest a few years ago, and literally began walking to the main stage the moment Down had finished the second stage, and when I got there, Black Label Society had already played. It was ridiculously stupid. I didn't understand that.
A totally wrong move for DF, in part because more of their true fans would be at Gigantour or even Sounds of the Underground. Sharon must have offered them more money, in which I wouldn't blame them. They'll also end up on the Ozzfest compilation CDs, which would be good. But for real live exposure, I think they're gonna come up short, and probably disappointed with the experience. Oh well.
