I don't know if I could pick the best... I've been to a LOT of good shows and some of the best were local Seattle bands playing in clubs downtown. But Rush was a standout, coupla years ago they played all of 2112... Weird Al Yankovic had a great show...
White Zombie and Pantera had a killer show together! Those are some of my fave BIG concerts.
