I've been all up and down the internet the past 2 weeks, reading about this band and the new album. I can't honestly remember where I heard about the whole Fiction and A7X fans thing, but it was kind of a "I read it in passing" sort of thing. It stood out enough for me to be like, "wait, wtf is going on".
I'm not generalizing all A7X fans. My dad is a huge fan of them, he does not like DT and progressive music, but he loves Fiction and the more progressive elements on the album as well as the more 'classic' A7X elements.
