So I saw Accept open for Kiss in '84, and they were good.
I didn't see the Powerslave tour.
I did see the Page and Plant tour, albeit earlier - April, 1995 - and I will say this: "The Song Remains The Same" in that show was the single greatest moment in a concert I've ever experienced. It was transcendent. I was with my buddy, who was a die-hard Zeppelin fan, and after the song was over I looked at him and he looked at me and we were like "what did we just see?" I know it sounds whack, but I felt like I was in a trance, like I got transported somewhere else. The power of music, indeed. It was so good. (And for the record, I was sober; I don't usually - usually - get wasted before shows, and didn't even then).
We also got a couple other surprises: "Lullabye", a Cure song (Porl Thompson was the second guitar player) and Plant sang "Shake My Tree", a Coverdale Page song. And killed it! Another highlight: Calling To You, Plant's solo song; the band brought it down and he was mumbling and scatting, and then as if from nowhere, he sang "For What It's Worth" by the Buffalo Springfield; the arena was dark, with red and blue lights and he was singing, then when he did the "Stop! Hey! What's that sound?" he went to his high register and the white lights from the stage came on... what a moment. Plant even then wasn't as good as he once was, but once he was as good as he ever was. That show totally changed my opinion of Zeppelin; when people talk about them being a live band, and having to see them when they were on, that explained it for me.
