Seems sudden after the excellent 2006 release "Astralism".
They have samples of 3 new songs on their website. A full version of the title track, New Revelation and then 2 1:30 samples of the songs Freedom War and Quisling.
The album sounds very promising from these samples.

Just go to the media section and click on the first playlist jukebox thingy and the top 3 songs on the list are the new ones.
Album cover seems pretty cool too, though its hard to see in detail, this is the largest I could find.
Pretty sure there are people on here that loved this band, cant remember, cant be arsed to check. I didn't even know about this album until just today so Im pretty stoked, Astralism was in my top 10 last year. I still need to check out their other albums however. Hopefully they are all as good.
