AC/DC perfected the art of immaturity a long time ago, but now they provide a perfect example for carrying that immaturity into middle age and beyond. Granted, this show dates from 1996, so they aren't quite geezers yet (late 30's), but they sure ain't kids either. That doesn't stop these overgrown boys from reveling in sexual innuendos and schoolboy smartass behavior. As far as rock and roll is concerned, the posturing is sheer brilliance. So is the playing. For two hours, the band tears through hit after hit after hit, with a precision that is truly startling.
