As for their sound, it's pretty much what you would expect from a traditional black metal band - low-fi production (at least, on their earlier albums), blistering blast beat drumming, frenetic tremolo-picked guitars, and raspy, harsh growled vocals. It's all here. I have every single one of their albums. I particularly like Pure Holocaust and everything from At the Heart of Winter onwards. I'm not sure what my favorite one is, but I tend to gravitate towards Sons of Northern Darkness the most, probably because it's the first one of theirs that I heard. If you've never heard of them and are thinking about giving them a shot, I'd recommend starting with either that album, Pure Holocaust, At the Heart of Winter, or even their newest album, Northern Chaos Gods.
Sadly, Abbath left Immortal in 2015 after a legal battle with the other band members over the rights to the band name. He's doing his own thing now under his stage name, and Demonaz and Horgh have decided to continue on under the Immortal banner. Demonaz did the vocals on Northern Chaos Gods, and he did a very good job in Abbath's place.
These guys are very talented musicians, but they're not afraid to let loose every once in a while and have fun. They're not a flat-out parody of a black metal band by any means, but they don't take themselves too seriously, as can be seen in the video for "All Shall Fall" below. I really like that about them.
