Nathan Salsburg’s 2011 debut was a beautiful ode to racehorses (a point of pride for any resident of Kentucky). Comprised of seven acoustic guitar instrumentals and one vocal track, Affirmed caused Popmatters to declare the record “one that others like it will soon be measured against.” His second go-round is a grander effort. Although still primarily composed of acoustic guitar, the songs sound bigger. They bounce along, weaving through unexpected twists and turns, with the occasional piano melody or fiddle line.
