Sturgill Simpson's new album, "A Sailor's Guide to Earth," is a lot of things: country, Americana, rock, soul, funk. But mostly, it's a love letter to his newborn son. Mary Nahorniak visits Dad Rock to listen and discuss.

"Tuesdays With Mary" is a weekly feature of Dad Rock, a music podcast from USA TODAY hosted by Patrick Foster and Jim Lenahan.
