She may have made fans wait for this fourth album of resplendent folk-pop heartmelters—it comes a long five years after Life in a Beautiful Light—but you can hear Amy Macdonald’s growth and considered care in every corner of Under Stars. The title track packs a triumphant country stomp, “Leap of Faith” rides an improbably smooth guitar line and “Automatic” evokes the freewheeling road anthems of a bygone age.
