Gratz on the show. Would have liked to see them in their prime, not so sure now honestly. My tastes changes to the mellow, and thier old.
With that said, seeing AC/DC, even very late in their careers, was an amazing and amazingly fun show, so Maiden, given their rep, is probably still a great experience.
They still have it. Bruce Dickinson still has a nonstop motor. He's running all over the stage the whole time, and still manages to sound great. Even Nicko went without any break in between songs. They still have it.
I saw AC/DC at Giants Stadium right before they knocked it down. They're still great. Angus is the man, although it's kind of creepy seeing an old man dressed like a schoolboy....
