Oops you're right they're on Kscope. My bad.
Anyway, I listened to everything except the last two albums ("Missa Atropos" and "The March of Ghosts") and I think you might wanna listen to their first two albums only after listening to the other stuff. The first two are great but aren't quite as polished as the other ones IMHO.
I'll definitely need to check out the last two albums though, should be awesome
