And they rule. You can find their/his (one-man project, y'see) demo for download quite easily with a quick Google search, or in the depressive black metal thread, since ~Neurotica was good enough to provide an upload.
Testament to their quality - I intended to give the demo a quick listen when I downloaded it, then come back to it later, as I was intending to head out to the pub. I ended up sitting and listening to the whole thing, without moving from my chair. I set up a PayPal account today specifically to buy it from Ars Magna. It's that good.
