Mastodon did not make their bones as a Prog act. They introduced some Prog tendencies on this new disc. And Mastodon is successful because they have a machine behind them. They have had a video on almost every episode of the HBB, have been on at least one Ozzfest, etc. Their appeal is to a demographic that you'll never see at a Pagan's Mind show.
I appreciate the desire Prog Metal fans have to try and claim bands like Opeth and Mastodon as their own, in an attempt to demonstrate that Prog has some market viability. But laying claim to these bands is tantamount to grasping at straws. These bands aren't popular because of their Prog tendencies, their popular in spite of them.
Zod
Throughout this thread, there have been so many random assertions with no backing. You claim Opeth isn't prog because their "best" albums were their first 5? LoL, as if that's a competent excuse dude. You can't possibly lay down that highly subjective reasoning as a serious argument.
I think Opeth's last 5 albums are their best, which are more progressive than the first bunch, therefore they are prog metal.
And Mastodon has ALWAYS been lumped in as a progressive, post metal whatever sort of band. In fact, do you not remember the Dream Theater comparison controversy from several years ago where some journalist compared DT to Mastodon asking how Mastodon was able to write cool songs but DT was strictly a "prog snob" band, and the dude basically laughed and made fun of the DT guys? That was a pretty big controversy on the interwebs.
Ultimately, after doing alot of thinking on this subject, I've come to the conclusion that there are two big problems with this thread. One, the majority of you, including Glenn, seem to define "prog metal" as 5 guys (bass, guitar, drums, keyboard, vocals) who play epic, majestic, oddly timed, slightly quirky, Rush-meets-Judas Priest-meets-Metallica sort of stuff. In my opinion, that's a load of BS fellas. Opeth's biggest influence is a British band called Comus, a prog rock band that doesn't sound anything like Rush. Not every prog band will sound like Rush/DT. If you do think that Rush/DT are the fathers of prog (which I think is a ridiculous idea), then yes, the idea of "prog drawing less fans than power" can hold true since there simply aren't many bands that have graduated from the DT school of things, and the majority of which who have are quite young. Do you not see why this comparison is unfair?
Between The Buried and Me, Porcupine Tree, Opeth The Mars Volta, Coheed And Cambria, et al are all progressive bands and they all outdraw Hammerfall and Blind Guardian by the buttload. This is the other problem. You cannot look at a genre and claim it is innately more popular than another just on the nature of the genre. There will ALWAYS be bands that outdraw eachother. Glenn brought up Fates Warning alot in this thread, as if to ask why they didn't sell out the show. The fact is, Fates Warning hasn't had a product out since 2004. That's FIVE years of no promotion, no label backing, nothing. I don't care WHO you are, a band cannot go 5 years in the dark like that and expect to sell out a show and get everyone hyped up. In Hammerfall's case, it's the exact opposite. They haven't toured in 4 years and the numbers for their last tour were abysmal. Had they stuck it out and done a few tours, I'd agree they would have been able to sell out the fest, however I don't think so right now. The band is losing its buzz and its relevancy in the US and I suspect Europe as well, which is their bread and butter.
