This is Katie Robertson, who sings with the Nashville-based band Stagolee. Her full-time job is teaching. Only in Nashville could your kid have a teacher who sings like this. Next week, I’ll post a full profile of Katie and her band, along with three more songs she sang as part of our “Songs From My Couch” series. In the meantime, here’s a preview — her masterful take on the old blues tune “Trouble in Mind.”
