Really catchy and melodic, the whole album has a nice flow and you can really bang your head to it. The production is very warm and sounds great cranked up loud.
Firmament’s sound places the album squarely within ambient black metal territory, more Drudkh than Darkthrone. As such it’s probably more likely to appeal to those looking for something like the former than the latter. Think Circle of Ghosts but with more thunderous kick.
