With their spruce arrangements and Big Star-esque chord changes, Good Old War cannily mixes folkie sentiments and pop savvy. Hailing from Langhorne, Pa., the trio makes sleepy-time music that adds accordion and other keyboards to bright guitars. Such tunes as “My Own Sinking Ship” and “Coney Island” reveal a bunch of neo-folkies with a sense of humor: “Coney Island” finds them crawling back to the big city they love, and elsewhere they blend indecision and good-natured aggression. Their music is too premeditated to be called purist, and you could say the same about the style of The Devil Makes Three, a trio employing stand-up bass, rough harmonies and 1920s blues chord progressions. Singer Pete Bernhard writes oddball tunes about the power of music, while the band shifts into double-time at the slightest provocation — you could say the group likes rhythm.
