NSR:s description is pretty good, but should be complemented with the band which first came to mind as I heard this, namely Drudkh. The problem is that I'm not that fond of Drudkh, but Häive's music somehow feels like "Drudkh done right" -- if the resident fanboys will excuse such a statement.
Tenhi is also an obvious influence. Häive offers the same same melancholic sweeping musical arrangement, but only partly through the use of acoustic guitars, and even makes use of clear chanting/singing from time to time.
The folk elements are nicely incorporated into the music, not so much by means of archaic instruments, but in song structures and riffs.
There's also a good amount of Burzum to be found, but then again, what band that want's to play dark, slow and atmospheric black metal can avoid that influence?
MP3:s can be found at http://www.mikseri.net/artists/?id=25121 and if you only have time to listen to one song, I would recommend Metsä Koskematon. A wonderfully dark song, packing tons of atmosphere, mainly through the fantastic main riff. It is however a bit harsher than the material from the upcoming full length.
What's more, their album covers are real classy:
