I have a friend who said the same thing, but I never understood why you'd go to a concert to stand there and watch from afar, even if the sound quality is better from further back. It's very uninvolving when you sit so far away. You may as well just listen to the CD.
Well for me, with the music I listen to, most of the venues I go to are small, so sight/involvement isn't really an issue.
And you can't be serious about that last line! There's no comparison!
