Since starting out in the late ’90s, the Finnish producer Sasu Ripatti—aka Luomo, aka Sistol, aka Uusitalo, and, most prolifically, Vladislav Delay—has carved out an implausible space at the intersection of house, ambient music, dub, and noise. A thematic companion to his Rakka LPs and 2021’s Fun Is Not a Straight Line, Isoviha is both one of his harshest albums and his most hypnotic, a landscape of static, sputtering engines and Arctic wind carved into neat, looplike shapes (“Isosusi,” “Isoteko”). Lighthearted, no. But there’s a persistent sense of wonder to Ripatti’s boundary-blurring that makes even the most forbidding sounds feel liberating: difficult art for everyday use.
