I don’t claim to know much about country music, but I like to think I know what will and won’t work on the radio. And after just a few listens to Susan Cattaneo’s single “Little Big Sky,” I see no reason why she won’t find her way on country radio stations before the year’s end. With a big bursting chorus, indelible verses and the kind of swagger one needs to make it on Music Row, Cattaneo has all the tools to make a dent. Here’s hoping it happens. These are hook-heavy, gorgeously crafted songs that deserve a wide audience.
