It's all one song! So proclaimed Neil Young on Year of the Horse and, yeah, while he made a neat point in a philosophical sense, the two LPs - across a total of four 12" records - up for this Black Sunday truly are one song. Except for when they're two. Or three.
It was not by design but instead a happy coincidence that recent receipt of what is quickly being acknowledged as the definitive release of Sleep's magnum opus collided with a massive Omega Music haul, all product emanating from doom-laden Southern Lord Records, and I ended up with two double-LPs each housing sixty-plus-minute single songs.
