From what I've heard, this is a hybrid of crust punk with some speed metal stylings, and a bit of black metal. Sort of like Iskra from Canada. What I did hear was very forceful and hard-hitting, but I'm unsure of the longevity of their material.
I'd like to address this band again. I recently acquired two of their albums, "Sekt" and "In Extremis". Both have seen heavy rotation in my listening habits, the first being much more black metal influenced, and the second being more battering. I would gladly recommend this band to anyone with an interest in Doom (UK), current Extreme Noise Terror, or perhaps second tier Swedeath from the early 1990s. Very solid material on both albums, one of the few punk associated bands I've heard which consistently develops an atmosphere. Definitely A class material, when it comes to modern punk bands.
