Sorry Sambo-Chris but I start to wonder if you have too much time or too much money that you can travel to all these concerts. I mean there're people who can't do that. Don't get me wrong but there isn't everyone able to leave work or school for one or two days to visit a concert. (and there's also the problem how to go there - not everyone has a drivers-license or/and a car and you can just laugh about the public transport)
