When Low started out in the early ’90s, you could’ve mistaken their slowness for lethargy, when in reality it was a mark of almost supernatural intensity. Like 2018’s Double Negative, Hey What explores new extremes in their sound, mixing Alan Sparhawk and Mimi Parker's naked harmonies with blocks of noise and distortion that hover in drumless space—tracks such as “Days Like These” and “More” sound more like 18th-century choral music than 21st-century indie rock. Their faith—they’ve been practicing Mormons most of their lives—has never been so evident, not in content so much as purity of conviction: Nearly 30 years after forming, they continue to chase the horizon with a fearlessness that could make anyone a believer.
