Honestly, with Sunset of Solemn Silhouettes, this is some of the best post-90s black metal I've ever heard. Katabasilisk is doing amazing things, I can't wait for the full album!
This might be my favorite GSR release which is saying a LOT!!! Super fun and catchy, instantly relistenable without sacrificing any of the lo-fi grimness that makes GSR's catalogue so great. Do what I do and drink a ton of caffeine and then listen to this at work and see how much you get done!
