I agree with the Arctic Monkey guy. Think of the carbon entering the atmosphere from all the transportation people will use to get to all those concerts, from all the power used by all those rock groups around the world--significantly more than would be used on a normal Saturday worldwide. It's nice to demonstrate, but by doing what you're protesting?
