Earth Wind and Fire are fantastic performers! Am not that big of a Chicago fan however. I have walked out on only two concerts in my life: Chicago, and Hall & Oates. I went to my first (and only) Chicago concert way back in 1971, at the Indianapolis Coliseum. Left the concert before it was half over. Years later, I did the same thing when attending a Hall & Oates concert at the Indianapolis Convention Center. In both cases, the bands just stunk. In my opinion, some performers should just stick to the recording booths! Chicago Transit Authority's first LP was outstanding. And Hall & Oates "Abandoned Luncheonette" LP is still one of my favorites.
However, Earth Wind and Fire is another matter altogether! I have never had the privilege of seeing them perform live. I have two of their concert dvds. I swear it is impossible to sit still while watching them!
