The scrawled and scratched-out lyrics on the band’s website, the quavering vocals, the images of dust and absence and longing — Frontier Ruckus is tapping into all the elements of that particular folk style wherein the songs (and singers) appear much older than their actual age. In the demos for their album The Orion Songbook — that’s not Orion like the constellation, but Orion (oree-un) like the suburban Detroit city & lake — this Michigan outfit seems to be dreaming back to the time when it took two weeks to travel from Detroit to Saginaw. Appropriately, tracks like “Orion Town 2” and “Mohawk, New York” are filled with an old-time, bare-bones aesthetic. Dig through the band’s website to find more downloadable demos.
