Cold Specks’ last record, I Predict a Graceful Expulsion, was the best record of 2012, a haunting doom-folk record full of spiritual allusions and hushed, mysterious songs. By comparison “Absisto,” the first single from follow-up Neuroplasticity (Out August 26 on Mute) is startling. It begins with a sustained drone — the kind of thing that might turn up in the opening moments of a Scott Walker song — before a queasy trumpet heaves out of the shadows and into frame. “All the screams of the past will come crawling out to get you,” Al Spx warns, and moments later, the song erupts — the kind of clanging, violent crescendo typically found in a Swans song. If Expulsion was a ghost weeping in the corner, “Absisto” is a demon coming to stake its claim.
