Julie Bennett Hume knows her voice is unusual.
She describes it as gravely, brassy at times. It can go low. Sometimes, she says, it's almost a yodel.
"It can do a lot of things, but it isn't as if people say, 'Oh, that's so beautiful.' But I can do justice to a song, and that's what I like about it," she says. "That's what folk music is about."
