Brutal, hard and most of it all unholy fast, the only compromise taken here in terms of Black Metal may well be the sound. Thanks to Peter Tägtgren skills as a producer it has a distinct drive and tightness while keeping its edge and being well aware of over production.
Far away from the usual muddy (or as some may say 'atmospheric') heights and mids only sound, this is Black Metal where you can actually hear and feel the bass rolling over you like, well, a tank at full speed.
