I like a lot of the "Blackgaze" stuff, don't care how much it vilifies me but I like bands like Deafheaven, Bosse-De-Nage etc. My one view on it though is, despite containing the elements of Black Metal, its closer to Post Metal for me.
I've been listening to Black Metal since I was at school, first thing I heard was A Blaze In The Northern Sky by Darkthrone and it blew my mind. I was, still am, a huge Death Metal fan but this stuff just harnessed a vicious raw energy that Death Metal didn't really deliver. May sound a bit far reaching for some but Black Metal was my Punk Rock. Early 90's never threw anything up as a radical as Black Metal. Obviously got a lot of time for all the stuff of that era, heck even Impaled Nazarene! Once it went a little mainstream and the symphonic stuff started to get everywhere I kinda walked away from the scene for a long time, missed out on a tremendous amount of great stuff I'm sure.
Delved back in the last 5-6 years and reconnected with the old stuff, picked up a few bands I missed and a few new ones along the way.
In terms of how, these days its anything epic and bleak. Discovering Weakling was a game changer. Early Burzum (As much as I loathe Vargs view on the world, despite a while struggling with it, I've managed to separate the mans twisted politics from the music ) is still the bench mark for me, Hvis Lyset Tar Oss and Filosofem are borderline untouchable . Mgla are another recent discovery I've really enjoyed.
After hearing Seven Tears Are Flowing To The River by Nargaroth I'm tempted to check out more of their stuff and am very much open to suggestions of stuff to listen to.
