It was with much sadness that we received news of the ”imminent demise” of Hydra Head Records. For nearly 20 years, Hydra Head has been altering the way we think about heavy (and, occasionally, not so heavy) music, while simultaneously perfecting the art of unbelievably badass packaging. Their absence will be our loss. On a small, personal note: given the countless ways in which Hydra Head’s output has moved and shaped me over the last 15 years, it’s an honor to be premiering one of their final releases. Requiescat in pace, HHR.

On October 16, Hydra Head will release a split 12-inch from Mamiffer (Washington) and Pyramids (Texas). Although both artists will be releasing unique compositions, there is (to shamelessly borrow from the very accurate press release) a unity of vision — both sonic and emotional — at work here. You can preview the full split below, so I won’t waste too many words. Suffice it to say, however, that it — all of it — is a strange, gorgeous, and sometimes overwhelming mix of acoustics and electronics. In short, it’s a stunning release. Think Grouper meets William Fowler Collins. Think Jefre Cantu-Ledesma meets Neurosis. Or, hell, just think “Mamiffer” and “Pyramids,” as both have long since established themselves enough to be the bands to which other bands ought to be compared.

Furthermore, a limited-edition photo book by Faith Coloccia is available with the clear/black vinyl for an additional $5. Considering the work contained in the booklet accompanying the Locrian/Mamiffer collaboration (a personal and TMT favorite), I’d suggest you spend the extra $5.
