Servant of Love is a different kind of record for Patty Griffin. Elegiac piano, muted trumpet, bowed bass, kalimba, a myriad of guitar, and a smattering of percussion are selectively employed to create delicate melodies with sparse, hypnotic arrangements. Jazz, blues, and world elements enhance Griffin’s folk and Americana base, and add mystery to meditations on love, human behavior, and the natural world. Her mood varies from hopeful to reproachful, to philosophical. Griffin’s once crystalline voice has taken on a weathered quality that evokes a wary sophistication. It resonates with the knowledge gained through surviving and triumphing over adversity.
