“Modderlaars” is the sort of track that is quiet enough to draw you in and dense enough to then creep up and surround you. By all rights, the minimal materials should seem tattered and light. And yet they accumulate with an unmistakable hardness, like thick musty glass, acknowledging the world but still blocking it out. Throughout is a steady pulsing that has a blood-in-the-ear intensity, especially on headphones. But much as the sounds are thin yet strong, the pulse is pounding yet slow. The result is an enticing sonic interiority. You can luxuriate in it, but you also cannot escape.
