Somewhere between swing and Americana, local folksters The Circadian Rhythms cook up bluesy ballads that with ease impress. Mixing a laundry list of instruments with creative deliberation, the band is like mash-up of Glenn Miller with beardos like Sam Beam. Vocals suggest hard times, long days, and nights spent drinking whiskey. Sounding older than their years, The Circadian Rhythms revive the rugged swagger of saloon goers long past with the ivory chords of “Stealin’ Honey” and the shuffling snare of “Sweet Lovin’ Mama”. Charming yet pastoral, these urban troubadours’ ballads will make you sing la-di-da. They’ll be matched with the experimental pop of Motorcycle Maus and the chamber pop of The New Heaven & The New Earth as well as Swedish indie rockers The Horror The Horror.
