I was pretty surprised at the results of the 'post your age' thread that was here a while back. The vast majority of people on this forum are in their teens (which would explain why this forum is so craptacular).
I never would have thought it before, but now I'm thinking that most Opeth fans are very young. But they do have something about them that appeals to all ages.
Just because most of the people who posted on this thread were teens, it doesn't mean most Opeth fans are teens.
I think that the younger fans (like me, 17) are much more likely to join the band forums in general.
I'm 36 and I've been a fan since I was 22 (16 years now if you're too lazy to do math). .
That's 14 years.
ah! now it all starts to make sense.(which would explain why this forum is so craptacular).
Id say it appeals to more of the older generation than the younger for a few reasons. For one, the younger generation aren't exposed to much of Opeth because it isn't commercial..... and it also may be musically/conceptually out of their grasp. Also, a lot of Mikael's influence is from past generations....and that would appeal to the older fan base as well.
