Passing Shades is an investigation of the metaphysics of loss and the transitory nature of the material world. But it is not a grim collection; over 8 songs, Group Rhoda diverges through synthesizer-laden symphonics, four-to-the-floor inflections, and cosmic musings. Barenbaum’s striking voice and singular songcraft guide us through this labyrinth. Arpeggiated waltz “Flow” channels wisdom sought through martial arts; “Earthly Ark” sets a Margaret Atwood poem from the God Gardener’s Hymn Book to somber electronics. The vocoded canticle “Nevermore” is dedicated to the memory of a beloved cat. ‘Passing Shades’ is both mystifying and revelatory. Folk forms are echoed only to detour into the alien. Each song functions as both a fragment of a larger puzzle and a koan unto itself.
