Okay-ish profile, but I like this bit in particular:

In “Sadie,” a ballad with a distinct Appalachian flavor, Newsom sings lines that could speak for thousands of musicians who’ve drawn on the deep well of American folk music: “This is an old song/These are old blues/This is not my tune/But it’s mine to use.”
