I'm going to hold out hope that that the "several" festival appearances Opeth.com lists are the Sounds Of The Underground (Yeah right), and the US tour will be a full headlining tour. I seriously doubt, and I imagine that the US tour mentioned will turn out to be this 18 band crap.
That said, if this festival comes anywhere near me, I will go, just because I want to see Opeth again no matter what, even if I have to force my way through a bunch of metal core kids in order to get as close to the stage as I would at a club. I can already say that most of the bands will bore me, and the summer Texas heat will only piss me off. But for that 30-45 minutes Opeth gets to play, I will be in in musical ecstasy. Then I will absolutely hate whatever useless band follows them, and will have to leave before I throw something at them and make an ass of myself. Also, if while watching Opeth, some little metalcore kid should Kung-Fu me, I'll take his head off.
Bottom line is, my personal opinion is that this tour sucks. But! If it makes Opeth money, and helps them do more headlining tours in the future, helps them continue to make a living doing what they love, that that's the important thing, and I'm all for it.
My selfish opinion is that I want another headlining tour, because I want as much Opeth as possible. I don't want to be out in the heat all day, waiting for them to play two songs only to have them followed by Norma Jean or some shitty stomp riffs for the next four hours. I want them to play to an audience that appreciates them, so that they can leave each show feeling happy about it, having enjoyed themselves and want to keep touring. I don't want them to go through the grinder, I've heard festivals are among the hardest tours to play from a band's stantpoint, and I don't want them stuck playing a crowd who doesn't understand or appreciate them, who may boo or ignore them, it's not fair to Opeth.
I've been waiting and hoping for over a year for another Headline appearance, and now it seems that may not happen. I've been telling someone how great they are, I have a drummer friend who's over 50, yet due to Opeth has an interest in extreme metal, and I promised to take him to see them when they return. Well, he's not gonna wanna go sit in the heat with a bunch of 14 year old Hot Topic metalcore mall losers, and I don't blame him. I want to give him the chance to experience the awe of a full Opeth headlining set, not an abbreviated, distorted muddy sound festival set.
It seems to me that the full awesomeness of the songs will be lost in a massive, daylight, outdoor venue. And that's just not fair to the music.
So really, I guess my main reason for being opposed to this tour is a selfish one, wanting to see Opeth in a club, headlining. Hell, even if they were headlining this festival that would be much better, at least they'd get a full set. But aside from my own interest, this doesn't seem fair to the band. We all know they've worked very hard to get where they are with their fans, they've gone from opening act to headliner in every country they play, they have a very loyal fan base who understands their music and appreciates all it's many nuances.
It just doesn't seem fair that they now have to play a shortened set for a bunch of little kids and knuckleheads who only want a stomp riff to "dance" and kung fu too. The real fans, those who actually appreciate them, and even those who they may be converting, will in all likelihood be lost amidst a sea of mediocrity, just as Opeth will be amidst the other bands.
That just doesn't seem fair.
