I only have Existence. It's a pretty good album. If you like Existence, you might want to check out their debut album, Swanlike. I don't know if it's as good as Existence though, since I've never actually heard it.

The new one promises to be something different again, judging from the short samples you can hear on their website right now. I also read Vurtox from Disillusion is doing guest vocals
