Is there really a rockstar that lives in middle TN?

My dad used to work for GM (he retired last year with 27 years) and a friend of his he used to work with said that a really famous rockstar from a really big metal band lived in Middle TN, and he said that he was from Denmark, or something. I heard it was Lars Ulrich, maybe Kirk Hammett, but I can't tell. So does anyone know?
