I'm listening to Beherit's album The Oath of Black Blood which I borrowed the other day from the local library.
They were one of the first black metal bands to emerge from finland, extremely lo-fi, thrashy scum -era napalm death esque stuff, but with production that's way more horrendous. It has some great songs though. Witchcraft!
