They're not really a band you can just listen to, rather you experience them. A few years back I bought "Through Silver In Blood", and listened to it on headphones in a darkened room. No bullshit, it was one of the most psychologically terrifying things I've ever heard, I would describe it as the aural equivalent of a snuff movie. It gives a new definition to "heavy", and is beyond mere music, this is art, in as much as it will trigger all manner of strange and disturbing thoughts. Definite;y a life changing record for me.
