Finally listened to this and at first I was like
...this is Darkthrone?? But, haha - the only Darkthrone album I own and know well is Blaze in the Northern Sky from 21 years ago. Yeah, I know - I'm a big black metal fan (albeit a relatively recent one) and have since travelled twice to your country in part because of this
, yet I am only familiar with one Darkthrone album.
For some reason I haven't done a thorough listening to this band, as I have most of the other influential black metal bands - their entire discography is on my (to listen to) list however....and I will get to it eventually. (with this new one, The Underground Resistance, that will be 15 studio albums to their credit in all so I've read)
Anyway...what threw me at first listen of the song you posted was the first part in particular that sounds speed metal-ish to me, plus the vocals are so different with some vibrato to boot! Starting at around the 2:50 mark though, it sounds a bit more like the Darkthrone of Blaze in the Northern Sky which I like very much.
I've recently been listening quite a bit to Satyricon (as I have many times before), and they still remain one of my favorite Norwegian bands.
