Maren Morris’ big-tent vision of country music shines on her breakthrough, “My Church”, which shouts out Johnny and Hank over a swaggering, stadium-ready stomp. She’s bringing other Nashville artists into the 21st century with her songwriting: Tim McGraw’s 2014 track “Last Turn Home” incorporates the huge choruses that echoed around early-’10s festivals, while Jillian Cardarelli’s “Rerun” combines a gently mournful vocal with weepy slide guitars.
