At the age of 63, Lonnie Holley is finally a rock star—at least for the moment. On a Thursday afternoon, he and his longtime friend, advocate and de facto tour manager Matt Arnett have stopped at the Community Grounds Café, a coffee shop in South Atlanta that doubles as a community center. They’re seeking some quiet in the mile and a half between their respective homes, and this, Arnett says, is a good place to find it.
