Non-LP tracks from an appealing New York chamber-folk ensemble that is sometimes undermined by its own slo-mo beauty. Sally Ellyson’s pristine soprano nicely parses the country-soul classic ”Rainy Night in Georgia,” while covers of songs by R.E.M. (”So. Central Rain”) and Fountains of Wayne (”Radiation Vibe”) are charming but bloodless. Hem’s Shaker-style Americana doesn’t rock, but seems perfect for period dramas. Hollywood sound designers, listen up to No Word From Tom.
