u2? Really? I've seen concert footage (no, I'll never go to one of their concerts, even if it was free) and I don't see the draw or why they'd be ranked so high. Bono is nothing special as a frontman, Edge just stands there, same with the bassist. *shrug*. I'd really like someone to point out a concert vid to me showing why they deserve to be on this list.
And I'd also put KISS a lot higher. Not just because I'm a fan, but they put more energy and showmanship into a concert than ANY other band I've ever seen. The who? no. The stones? no. Kiss? Yes, the most energetic and fantastic stage show on earth. Pink Floyd puts up one of the greatest light shows ever, well they used to. I think Trans Siberian Orchestra has everyone beat in that category now.
