Ultra

Editors’ Notes Zomby’s fourth album cements his place as one of techno’s most seductive doomsayers. Riffing on robotic soul (“Fly 2”), nightmarish video-game blips (“Yeti”), industrial churn and heavy-lidded trap (the Burial collaboration “Sweetz”), Ultra evokes both menace and calm—the sound of something lurking in an alley just around the corner.
