Reissued and expanded for its 15th anniversary, Max Richter’s The Blue Notebooks, a heartfelt protest against political, social, and personal brutality, remains ahead of its time. The album’s original mix of electronica, classical elements, and sensuous, textured sounds was a huge influence on a new age of composers, and is now supplemented with new arrangements, remixes, and the previously unreleased track “A Catalogue of Afternoons.” “On the Nature of Daylight”—presented here in full-orchestral splendor and with a version that includes the haunting voice of Dinah Washington—has become a go-to piece for TV and cinema soundtracks, while “‘Iconography,” with its cascades of organ, almost single-handedly spawned a new dawn for film music.
