Speaking very generally, black metal can be divided into two, distinct subgroups; the raw and the dirty, with its roots in punk, and the more "musicianly," with expert playing, and grander, more-"orchestrated" concepts. Either way, to pass my filter, the songwriting is key, and has to be there to bring the sound across.
Naturally, there's been significant cross-pollination of these two basic styles over the years, and One Master are perhaps the finest example of a band that has chops to spare, with longer, epic songs, but with not an ounce of grit sacrificed—in fact, the sheer gut-punch of this session, as well as One Master's two full-lengths and split cassette with Glass Coffin, will simply bowl you over like a life-affirming ass-kicking. Even as I listen now, after many a deep sit-down with the material, the ferocity of One Master's Castle session is staggering and the first thing your ears will notice—melodic riffs, deftly arranged and well-written songs, delivered with mighty, mighty force.
These guys were also great to hang with, and we had lots to jaw about off-air, with our shared obsessions for classic horror / exploitation film and the like. These are men you can have a beer with, and talk about Cannibal Ferox on into the night. I recall saying, "Is there any scene in Requiem for a Vampire other than the basement-torture scene? 'Cause if there is, I don't remember it...." hehe....
Thanks a fuck-ton to the band for bringing their exquisite black-metal art to WFMU, and to engineer Juan Aboites for creating a clean, solid and forceful mix for the broadcast. Thanks also to Tracy Widdess of Brutal Knitting for re-crafting my shitty iPhone band captures.
