Ellen Arkbro’s fourth album, Nightclouds, collects five improvisations for solo organ, recorded across Central Europe in 2023–24. Nightclouds is more unabashedly Romantic and introspective than her previous efforts, though it remains firmly rooted in the rigor and precision that have come to define Arkbro’s concept. Extending her previous explorations of spatialized harmony, tactility, and texture, Arkbro draws equally on sacred music, ECM–style jazz, and downtown minimalism, conjuring a cool intimacy and tone.
