Folk may be an old, old genre, but that doesn’t mean everyone has given up on trying to innovate it. Take the latest project by Somerville band, Eternals for example. On Isn’t That Any, the quartet intently root their music in the… rootiness of their lead singer’s voice and snare-heavy percussion typical of folk, but on each track they also mix in a different genre or influence seamlessly, giving the album a broad musical width while still maintaining a strong investment in folk. One intriguing moment in the record is when they segue directly from "See You," a song drenched in shoegaze, to the alt-folk pop jam "Bar Room Dancing." At other times they even bring in some synth textures – perhaps signifying the emergence of "synth folk" as a genre? In short, it’s always nice to see someone take the old traditional American music with open mind and heart, and Eternals have done just that on this latest LP. You can check them out at Lilypad Inman on 7/22. —Henry Solotaroff-Webber
