I have mostly found the big arena concerts to be disappointing. This mioght have had somthing to do with the "preparing " we used to do, to go to a big concert....I would often end up falling asleep. Also, speaking in a very general way, if a band is popular enough to fill an arena, they are a bit too commercial for my taste, and a little boring.
Probably the best concert I ever saw was Renaissance, in the mid to late seventies when Annie Haslam was the vocalist. It was in Toronto's Massey Hall, which was a great venue; a lot of my favorite concert memories come from there.
