Okay......I shouldn't have phrased it that way. But I respectfully disagree with you on this issue.
I hate boundaries in music. Real progressive music is no boundaries. And the problem is, that all of the bands are so different, and many of the bands I posted are basically completely unrelated, and you would never see a tour between the two bands. I basically see a trend of having one or two progressive, what would be called oddball bands pre Prog-Power. Even so, I couldn't ever see most of the bands I mentioned appearing at Prog-Power, because they would just be so out of place, because that's the definition of progressive. Prog-Power II is the most balanced lineup in my opinion of real progressive, prog, and power metal.
Some specific examples.....
Band: Fantomas
Influences: John Zorn
Scene: Avant-Garde Jazz (but they're still metal)
Band: Solefald
Influences: black metal, classical, prog-rock
Scene: Norway's Post-Black Scene
Band: Spastic Ink
Influences: Watchtower (duh), modern chromatic music
Scene: American progressive metal (thrash fans/"prog freaks")
On the other hand, I think most of the even "prog" bands at Prog-Power could be identified with a more standard set of influences, even if they are from different countries. It's more of a set of influences, and then an x factor that gives them their own sound.
You can't deny the huge chasm between bands that are prog as in changing rhythms, time signatures, lots of solos,(Dream Theater/classic prog-rock influenced) and then the progressive bands that are breaking boundaries and doing new things, sometimes labelled as "avant-garde." (no standard set of influences) Pain Of Salvation basically have it great because they are truly progressive, but still are in the arena enough to go over well at Prog-Power. Orphaned Land are the oddball this year. What connection do they have "scene-wise" to the other bands? Nothing. Their sound is still standard "metal" enough to go over decently with most of the Prog-Power crowd. It seems so obvious, for example not having many bands from The End Records, who are even a merchandiser at the festival. They're metal. They're progressive. But they don't fit with what the general "feel" of the festival is. Based on my feelings from this forum, I can imagine what the reaction would be like if Fantomas or Solefald or Ulver or something were thrown in, it would be like throwing a wrench in the whole operation.
To stress, I have no issues with the festival, the lineup, or anything, it's very well done. I'm just calling it how I see it. I simply respectfully disagree with your assessment of progressive music vs. prog-metal.
