A lot of them would make my list, but the order would be changed quite a bit. I don't think I could exclude Rush, but they're no longer the draw they were for me. I'd probably give them 10th just out of respect, but I doubt I'd even go to see them again. Certainly not for their asking price. The new material and Ged's voice just don't do it for me. While Maiden would be a top three, they might drop a notch or two since this tour seems to be where Bruce's age caught up to him. He still sounds very good, but not like he did 3 or 4 years ago. Plus, the fact that we yanks only get greatest hits tours doesn't help their case any. Not sure where I stand on Roger. Spectacular thing to see, but it's hard to call his show a live band. Metallica would be a lot higher on my list. I suppose it's a matter of taste, but I find spontaneity as important as sheer precision. Now that Dream Theater are all about performing the perfect show every night, Metallica is really the king of going out and surprising people. My opinions on DT are already well known, but suffice it to say they dropped a whole bunch of slots around, I dunno, three to five years ago.
Never saw The E Street Band but would love to. Don't like Springsteen very much at all, but I'd definitely dig the show.
And I would have included Dio in my list. He always sang what he felt, which varied from night to night, and no other artist did as much to make the audience feel like all he wanted to do was please them. The man's graciousness really affected the shows.
