I know of Alcest and Amesoeurs. Haven't listened to a lot of their discographies yet. And literally the only song I've heard from Deafheaven was Sunbather, honestly not really my cup of tea either. I'll give these other bands a listen.
I'm still not too familiar with the genre. I tend to stick with what I like when I listen to black metal in general. Currently I really like Harakiri For The Sky and Lantlos. If anyone could recommend me some similar bands that would be awesome. 😊
