At once rootsy, elegant and a little mystical, the Wailin’ Jennys advance their art further on Bright Morning Stars. Members Ruth Moody, Nicky Mehta, and Heather Masse pool their talents as singer/songwriters to create a luminous harmony-centered sound fusing contemporary folk, traditional hymnody and vocal-jazz styles in varying measure. The trio moves easily from hip-swinging rhythmic tracks like “Mona Louise” and “Cherry Blossom Love” to Appalachian-accented folk ballads like “Bird Song” and otherworldly a cappella pieces like the title tune. Lyrically, a spirit of resolve through hard times resonates within these songs, heard in the billowy opening tune “Swing Low Sail High,” the stirring, Indigo Girls-like “You Are Here” and the waltzing closer “Last Goodbye.” The Jennys wail most righteously on “Storm Comin,’” a defiant tune with the earthiness of a Southern spiritual. Mark Howard and David Travers-Smith’s production keeps the trio’s voices front and center, surrounding them with tasty acoustic textures along with electric guitar, brass, and understated percussion.
