Revocation, what a find! I also stumbled across Obscura at around the same time!

I once purchased Oranssi Pazuzu's debut via an American Ebay shop, but the guy sending out the CDs totally fucked this up and I ended up receiving first Panopticon's "Collapse", which was the best random discovery I can remember, then a couple of days later a copy of the Oranssi Pazuzu album, and eventually another copy of the latter as well as Ezurate's "Blasphemous Hierarchy" (quite ok, I guess, songs on Youtube didn't make me want to listen to it immediately, it's still unsealed), because I had complained after the arrival of "Collapse" about the mistake and seemingly it wasn't noticed that the right album was on the way already. 4 CDs for the price of one, quite a good deal. Even though I have to say that I don't listen to the album I originally wanted nearly as often as to the Panopticon album.

Love that OP discovered Xasthur through a Furrey board. I had no idea the furrey community was so true!

There's a few of them Emperor, Dark Tranquillity, Epica, and Death.
