There is a summit at Hamburg this June! If I could afford tickets to see linkin park all over the world I would really go. Is Hamburg a festival or single gig? Your english is awesome, I know a couple of Danish people, I think its about time that british folk started learning some european languages. The i tunes festival in london is free, you've just gotta apply for tickets on the i tunes festival website.
Were the band friendly? they must do so many meet and greets!
