At the heart of Minor Moon’s open-ended and knotty country rock songs is an undeniably inviting lightness. While the Chicago-based songwriter and bandleader Sam Cantor writes impressionistic songs about the end of the world, they’re wrapped in such a warm blanket of lush guitars and pastoral twang that they always leave a hopeful spark. On their latest LP, The Light Up Waltz, Cantor sings of the fantastical in magical traveling bands, swaying bridges, and aquamarine metamorphoses. Still, he’s concerned with fundamentally human questions about who we are and how we reinvent ourselves when everything crumbles around us.
