Hmm...that's a tough one.
But I'd have to go with U2
. I've seen both bands a couple of times and they've put on amazing shows.
But IMHO, U2
still has some new musical ground to cover.
The Stones were incredible. Just seeing Keith Richards live (and alive, for that matter) and hearing his one-of-a-kind guitar was a real treat. But I got the impression that the Stones were just focusing on their older material. Nothing wrong with that. From a marketing point of view, I suppose that's a viable approach. There were plenty of fans on hand to see them.
Don't get me wrong -- I love the Stones. But their new stuff just isn't up to par. It's good, but there's no way a "Bridges to Babylon" can measure up to "Exile on Main Street" or even "Tattoo You."
