For a decade (encompassing five well-received albums), Horse Feathers were known for delicately gorgeous acoustic folk songs, often dressed up with orchestral arrangements and anchored by frontman Justin Ringleโ€™s cerebral lyrics. But on 2014โ€™s So It Is with Us, the Portland-born institution started prudently exploring new sounds, tempos, and textures.

That exploration blooms in full on the bandโ€™s new record, Appreciation, released earlier this month via Kill Rock Stars, which finds Ringle, longtime violinist Nathan Crockett, and a new rhythm sectionโ€”multi-instrumentalist J. Tom Hnatow and drummer Robby Cosenza, both Lexington, Kentucky-based session musiciansโ€”ripping through country-rockers, stirring soul jams, 1970s-inspired pop, and gentle Southern boogie. These arenโ€™t necessarily twang-punk scorchers, but they also arenโ€™t reflective of the old Horse Feathers.
