Interesting point. I've never been able to get into the Stones music as much as many others. My parents saw them in Wichita (yes, i'm from Kansas) and they said it was pretty awful. This coming from my parents who, in 1973, saw Pink Floyd's DSOTM tour and brought in brownies to share with their group, including the security guards. (yeah, my parents are fucking awesome)
I'm not saying that people don't pay the pricetag, but the only time I'd pay over $200 for any kind of ticket would be if Pink Floyd resurrected itself from the earth with all the members (though their Live 8 was pretty damn close to me getting a passport), or a few other bands. But it's really difficult to justify paying anything over $100 to many of these performers when given their income over mine, lol. $100 to me is pocket change for them, but buys my groceries for a month x3
With that said - no U2 wasn't spiritual to me, but it was a good show. Springsteen back on the Rising tour was probably similar to your experience - having actually moved to North Carolina by that point, and I flew back to Kansas just to see that show. (well goddamn fucking worth it, too.... and getting busted taping by the security guard just to see him go "meh, screw it, you got away with it and I didn't catch ya."
And there are plenty of parties to be had, but most of those shows are either local bands, or bands I've listened to in the backs of clubs at 12 am pouring their fucking hearts out.. akin to the stones. One of the best bands I ever have had the pleasure to see (28? times) was The Urge... that was a fucking party every time they took the stage.
sorry for all the cursing, I'm just too damn tired.
But I do see your points, and it's refreshing to see music still touching people as such.
