As far as here in the U.S., a good example of what's popular amongst the kids was the Evergrey, Iced Earth, COB show at the HOB, in Orlando, around a year or so ago. Most of the kids were there to see COB, as evidenced by all the COBHC t-shirts. But what was reassuring is that there was some good applause from them when Evergrey opened though. Although I think that it is an injustice, IMHO, that Evergrey opened for COB, but obviously who opens and who headlines isn't about taste. It's about which bands those kids will spend their allowance or after school part time job wages on. It seems that bands like COB, Killswitch Engage, Cradle of Filth, Dimmu Borgir, In Flames, Lacuna Coil, Slipknot and Korn will get more of that than Symph X, EG, DT, Kamelot, Epica, Dreamscape, Pagan's Mind and Redemption (although I will say that Nightwish and Within Temptation are approaching that level of fame now). But I hope that changes to some degree (with the minimal amount of poseurs of course), since it seems that it's more about what the kids or older mainstream music fans want, then the rest of us. That way we can get more touring from these bands!
